First of all,
welcome, Kathy. This is absolutely a place you can hang your hat and call home. We promise to help and support, and give as much knowledge as we have --- which, collectively is a great deal! We all follow different plans here. I know that there are some among us who quite happily follow WW, but I think I'm correct in saying that most of us here don't currently. And if you have any doubts about whether you can successfully lose weight without going to WW meetings, then take a look at our Lose a Ton thread and there's proof positive!
As for getting started, you've done it! The first steps are to reach out for support and gather information. Great job on both counts!

I'm sure a bunch of other folks will offer advice based on what works for them, and it's really important that you listen and see if what others do will be sustainable over the longterm for you.
How you lose it will be how you're going to keep it off. In other words, if you lose it by following some diet that you hate or that is really hard to sustain, then chances are you're going to gain it all back and then some once you return to "normal" eating habits. The key is to make
lasting behavioral changes.
Forever changes.
We're all different, and what works for one might not for another. So do due diligence and spend hours on this site reading the different plans. Then -- and this is important -- I'd recommend that you buy a book called "Thin for Life," by Anne Fletcher. It's widely recognized as one of the definitive books on maintainers -- those who've lost weight and kept it off.
It's also important to make up your mind that you're in this for the long haul. It didn't go on overnight, and it won't come off overnight. Try to be patient, and celebrate every success, no matter how small it might seem at the time, or how it differs from what you were hoping for. Back to the long haul, it's REALLY important that you understand and remember that no matter what your rate of loss, time will pass regardless. So let's go conservatively and think of a pound loss per week, just for the sake of this exercise. At one pound lost per week, 6 months from now you'd be 26 pounds lighter -- almost halfway to goal! Now if you didn't think longterm, you might be all bummed out while that was happening, saying, "God, I only lost one pound last week!!" -- but if you were doing nothing to change your life, 6 months later you'd still have those 26 pounds and probably a few more. Choose to take control over how that time impacts your waistline and energy level.
Another related thought: Loss is the result of a thousand decisions made with the following in mind: Losing weight is my priority. It's more important than ____________. (Fill in the blank.) You won't make the right choice 100% of the time, because you're human. But the more the positive ones outweigh the ones that don't support your goals, the better off you'll be. If you get off track, no problem. Don't beat the crap out of yourself; pick yourself up and say, "I begin again NOW." That whole all-or-nothing "don't throw the baby out with the bathwater" analogy definitely applies here.
Planning is key. Once you decide how you're going to proceed, set yourself up for success by planning your meals, preparing them in advance if you need to (I do that every day and consider it critical to my success.) Removing the choice in the beginning can be critical to setting you off on the right foot.
For what it's worth, here's what I do, and what I'll do for the rest of my life:
* I count calories (like 1300-1600, depending on exercise) and fat (about 20-25% of my diet.) (I have a
lot of other nutritional goals that I set, monitor, and track, but you don't have to be as intense as I.

)
* I follow a low-glycemic diet (google it and you'll see a lot of info on why it's good. It means that the carbohydrates I eat don't turn to sugar as quickly, and give sustained energy rather than more readily turning into fat. Pasta, for example, when cooked al dente, is GOOD, not evil.

)
* I drink 140-160 oz. water per day.
* I make sure to get about 40% of my calories from protein -- I do NOT skimp on the protein. It helps you feel full for longer, it helps to sustain your muscles, and it doesn't weigh down your energy like carbs.
* I go for a high fiber diet -- like 40-50 grams/day.
* I restrict my sodium. (I average like 1800-1900 grams/day.)
* I log all of my food and exercise religiously in a nutrition/exercise/diet software program called
Diet Power, which I (and some others on 3FC) love, but lots of people use
Fitday, and are very happy with it.
* I exercise now about 5 times a week, but I keep telling myself I'll do 6.

* I spread my meals throughout the day, eating breakfast, a mid-morning snack, lunch, a mid-afternoon snack, dinner, and (usually) an after-dinner snack. At every meal, I have a protein and a carb -- almost never do I have a carb without a protein to accompany it.
* I take vitamins and supplements.
This is what I've done since the beginning (with the exception of the exercise -- I used to do it less frequently than I do now) and at the time of this writing I've lost 72 pounds since March. I'm 40, and I have an office job. And I started out about 60 pounds heavier than you. You can do this, Kathy. Do your research, and set yourself up for success. There are two schools of thought about how you start out. Some people believe in baby steps, and recommend you build upon your improved behaviors. Others -- and I fall into this category -- need to just do a total overhaul on their lifestyle, and just dive right in with a "lifestyle makeover." Baby steps wouldn't have worked for me, but they do for some others.
So there we are.........this is a long one, but I wanted to make sure that I was giving you all that I thought you needed. I'm sincerely excited for you, and I wish you every success. It's 80% diet and 20% exercise. And it's 100% head work. Set your mind, be kind to yourself and change your definition of "reward," continue to come back here for support and renewed focus -- and the occasional kick in the *** --- and you'll do just fine.
Yay, you!
