I think I need help

I made a post about 3 or 4 hours ago about feeling depressed. After making the post I started to feel really sad so when it came time for lunch I completely neglected my need for food. This has been going on for about a week or two and didn’t realize till now. I have had trouble with eating in the past. Last year I was on the edge of being anorexic. I just... I feel so fat. I weighed myself earlier and I gained 20 pounds since last year. I’m now at 145lbs. Almost the same as my own mom. I guess I just need some advice.
