Depression and weight gain

I used to be extremely fit... and guess I took my health for granted. Now I'm in my mid thirties... about 15 lbs overweight and just CAN'T seem to lose those extra pounds! I went through a bad phase two years ago. Tried eating my way out of depression... which just made things worse!!! Things got much worse when I realized that I don't fit into our friend circle anymore because of the way I looked. Now I'm trying to get my life.. and my health back on track. I'm looking forward to finding friends here who can understand the struggle and build mutual support through this journey towards fitness
