Anorexic to overweight

I’m 21 years old and have severe body dysmorphia and have struggled with anorexia since I was 15. I used to be 115 lbs (I’m 5”4-5”) and I maintained that until after college. Before I was pregnant I was my heaviest at 145. Today I had my confirmation pregnancy appt and I’m a whopping 150 lbs. I’m 5 weeks and 5 days pregnant and it’s extremely difficult to deal with this weight gain but I refuse to stop eating. I’ve been so depressed and crying so much and my bf has been supportive but gets tired of constantly having to reassure me I’m not ugly lol. How did you girls deal with the weight gain? Are there any tips? Please help 💕
