Kira was right on the money
just wanted to offer some hugs and tell you you can do this!

ditto!! You are soooo young, sweetheart, this is great that you realize you want (need) to be healthier and you can only improve everything in your life by doing so....I remember the part of feeling so bad about everything, it then affects those close to you...you're wise to see it and want to change that!

The changes might seem pretty tough at first but then all changes in habit are, I urge you to come here to 3FC whenever you feel you are faltering and need strength and support, that's what I do and it always helps. best wishes!!
