oh tony, sorry you're so sad, now I understand u better.

But lenny is right, u have to start to find solutions. Once you start I bet u will feel better. U have to talk about this with your gf, and plan a strategy. I understand your gf also.
i know how hard it is to lose weight, being overweight myself, but I'm trying to reduce my intake of food... i usually eat because I'm anxious.
I think you have a positive side though: since your gf and u have the same problem you can work it out together. I think u can improve your quality of life and get back on the road.
Think about what's making u overweight, not just because of the food, but what's going on inside u. U say your gf has low self esteem. Why don't you go to therapy together to talk about this and work it out together? My best wishes, Rappaccini
