Newbie

I am a first time dieter. Trying to get my health and diet under control. Medical issues are affecting me and I am in need of a better plan :-)
This is a first time diet for me. I never had the need to lose weight because my thyroid worked properly and I exercised regularly. Now I am not well and not getting enough exercise. I am hopeful that between my new doctor I meet next week and my new diet and exercise plan, I can lose the 30 lbs I gained when my thyroid went bad. It is very hard, because I am used to eating what I want and plenty of it! Also, I am getting a bit depressed not being able to work out because health issues are affecting me so much
