Hi Heather
and
Wow! I started at the same weight as you, and we have both picked the same goal weight. I may have actually started a little higher, I'm not sure.
Yes, it does start one pound at a time. I lost 1/2 of my weight very slowly over a period of 5 years. (not recommended) The good thing was that I kept going down over those 5 years, not up. I changed alot of bad eating habits (but not all of them) and added exercise.
The better news, is that you got here to start your journey. I would probably be maintaining for several years had I started here. I find this support network to be unlike anything I could have ever imagined.
I think it's a good idea to find a "plan" and stick with it. If it doesn't work out, try another "plan". I picked SB because I didn't want to count calories and I was already eating healthier. It's working for me. Others are very happy counting calories. Honestly identifying your "issues" may help you to find your spot here...sugar, carbs, binging, depression, medical issues...
I think the most important thing is to find a forum to call home and post every day. Some of the age based forums would be a great place to start. After 4 months staying OP, my group knows my ups and downs, and I know they really care about me. It really helps when I'm not getting support at home.
Feel free to send me a Private Message if you ever want to chat. Very important is to hang in there. Sometimes I get off track for a day, but never longer. It does get easier.
Scared of failing...again.
I am worth it! 
Heather.
I am trying to do home videos;30lb shed and yoga for now....onwards..Heather
