Hi BuuBuu -
Welcome!
I started close to where you are now. I am 56 years old and work part time.
It's important to realize that we are all so different in our journey, metabolism, exercise, food we like, lifestyle, family, and more. Keeping that in mind, I'll tell you what I've done this past year:
I started out eating between 1600 - 2000 calories a day. As I started losing slower - I slowing had to change it to a lower number. Now I eat 1200 - 1550 calories a day.
I eat lots of veggies, fruits, lean protein (chicken, fish, turkey, beans etc), lowfat or nonfat dairy (I like ff milk, 2% cheese and ff cottage cheese), good carbs (whole grain bread, brown rice, pasta, sweet potatoes, crackers), & I aim for healthy fats (olive oil, canola oil, I Can't Beleive its Not Butter Spray). I love natural peanut butter and almond butter - I eat it every day. And - I also eat beef, pork, chocolate, and other goodies once in while. I used to eat ice cream, cookies and/or candy every day. Now I do have them...just once in a while.
I keep track of my calories, etc in a paper journal (lots of folks use online food logs) If a food doesn't come with nutritional infor I find it usually :

I do meditation and guided imagery almost every day.
I do stretches and some movement 3-5 days a week.
I drink lots of water every day- aim for 8 glasses.
I weigh once a week.
I plan my food everyday and then write down everything I eat - planned or unplanned.
I weigh and measure my food.
When I go to a restaurant - if possible - I check on line and decide what I'll eat even before I get there.
I need to eat protein of some form at breakfast - if I don't I am wanting food again right away.
I've been at it almost a year and have stayed with this program most of the time. If I go off for a few days or have a binge...I forgive myself and get right back on my plan.
My body doesn't ever tell me when or if I am 'full'. I think that part of me is broken. I wish it worked. So, I need to figure it out in advance and try and stay with my plan.
It kind of seems like alot of 'stuff'. But, it's the first time in my life that I've found something I can stick with for more than a few months. It's almost a year now. Doing these things has given me sanity with food.
Even if I don't lose everyweek (of course, I WANT to lose everyweek) - as long as I have had sanity with food - I am happy and grateful.
I also post at the 100 pound forum. (it's a good one, too) Here's thread from there about foods people find helpful for staying on their food plan:
