Eating disorder

I'm posting anonymously because I don't want hate.

Okay here goes.

When I was 14 I developed an eating disorder, it was EDNOS (the name has been changed since then), I restricted my calories to about 400-500 a day and exercised a bit, and purged everytime I ate so I ended up with less that 400-500 calories a day. It got to the point I didn't eat for 10 days in the hospital and lost 15 pounds and almost had to have a feeding tube put in, the only reason I didn't was because I drank the protein shakes they gave me. Fast forward to age 16, the same thing happened except I was throwing up what I did eat, which was only like a cereal bar a day and several protein shakes. I didn't eat anything for 4 days then only cereal bars and coffee and protein shakes for 10 days and lost 20lbs in that time. Fast forward to 18 I am living on my own, and stopped eating completely then feel into a binge/purge cycle, after a restriction and laxative and purging cycle, and only lost about 10 pounds. There was many months I just wouldn't eat most of the month and got super sick, and then switch to a binge/purge cycle because my body was starving. I'm turning 20 in January and I just had a baby three weeks ago and I'm really upset about my body and can feel myself about to relapse and in the process of relapsing. Have any of you mom's had a eating disorder and then relapsed right after birth. I'm overweight so it's hard to get people to take me serious when I want help. The picture taken was from 3 days ago. I've lost over 20 pounds since I got pregnant.

Edit: I didn't gain a single pound during pregnancy and am actually smaller than when I got pregnant but it's still to much weight.
