Trigger Warning; Trouble Eating

17 w 1 d and I'm having really hard trouble eating. I'm in 12th grade and when I was in middle school and freshman year I was anorexic. I over came it and everything but the thought of gaining weight still freaks me out a lot. And now my body isn't use to eating a lot and I'm really tiny. Before I got pregnant I was 95lbs. And before now I had no problem eating at all. I ate small portions of food through the the day, all day long. And now I eat in the morning and maybe something when I get home. I got sick a while ago and after that I started having nausea, but now I'm just scared to eat. I hate throwing up, period. Like its my biggest fear. But I feel sick all the time and I just don't eat much anymore. Anyone out there having the same troubles ? Or have some advice or courage get words because I really need it.
