What part of San Diego are you from? I just found this forum and we also live in San Diego in the Ocean Beach area.
I would be happy to workout with you if you are looking for a partner who's been where you are at.
After my 3rd child was born 17 months ago I went on a huge eating binge and was almost 40 pounds overweight. I could blame postpartum depression but the truth is that that only lasted a few months - the eating part I kept up with on my own
Anyways, let me know what I can do for you. Diet and exercise alone can get the job done. But don't make yourself miserable. Start with just 1 simple change, like an apple first thing in the morning for a week, then a 10 minute walk each day the 2nd week, so on and so forth.
You'll find your groove, just go slow.
