Hello, and welcome.
I believe you will find a lot of support on this site, and I'm glad you're trying to better your self. The first step is realizing the problem, and second step is doing some thing about it. (That's what my best friend told be before I decided I wanted lose weight for my health.)
It certainly is true though. I'm still very new to this site, and do NOT have much experience with successful dieting. But I started about over a week ago now. And so far I stayed strong (I'm really bad with food too)
I really hope every thing turns out well for you. I'm around your weight, so I know what it's like to easily get out of breath. That started happening to me..when I was just chilling, sitting down, I'd lose my breath. It scared me, and I was like.."I'm done with this!" I've been super unhappy for a very long time. (Lost my Dad in 08, then my mom in 09) So been through alot, dealt with a lot (including non stop family drama) But I've been pushing my self to be more active lately. I know you're a lot older, and I really do hope things turn out well. Try eatting healthier, (its so hard, but youll feel better! promise) and do small excerises, like lifting your leg while your sitting afew times, arm movements, stuff like that. I figure any excerise is better then none!
Best of luck to you Musicman, and I'm always here if you wanna chat! Take care!
