trig warning those who struggled with eating disorders and pregnant

Claire
Hey so I am 16 weeks pregnant and already getting panicky at the thought of gaining weight so I can be healthy for Scampers (nickname for baby). I was never officially diagnosed but concilipr a few years back thought I had EDNOS (eating disorder not other wise specified) and didn't have extra help other than (what I felt at the time) my friends forcing me to eat. Is there a way to get over the fear of gaining weight. I lost a bit during first trimester and just getting bump now.
