Eating disorder, depression, etc and weight loss challenges

Options
I have dealt with since i was 14, purging or not eating. I was very active and never overweight until my car accident when i was 18 in 2002 and since then have gained a LOT of weight and the eating disorder got a lot worse. I also have major depression and BPD etc. I am struggling with making myself eat, my doctor said i was gaining from not eating enough. I have not purged in 2 months and last month i lost 6 lbs by eating. I have been on this site 5 days and have not weighed myself yet but it helps to have this structure and knowing im doing ok with what i eat by tracking everything. It is a struggle to force food down though.
