hey everyone, im trying this out for the first time and have read good things about here from other posts.

Last year I lost 25 lbs after a huge break up (from a 3 year relationship) it was my new start and i felt good about it. Recently I was laid off and didnt have much motivation to watch what i ate or exercise. I fell into a slump of sitting on the couch and at the computer which resulted in my gaining everything back

I start my new job on Monday after not working for 4 months. I want to loose all that weight again plus some. I am looking for support from others, since my best friends (love them as i may) are enablers. They are my family, but we always eat out and at late hours. If others could give me advice on how to do things healthier and still hang with my friends but make better choices i would appreciate it!
