Stressing!!!

I'll be 36 weeks tomorrow and constantly stress out... Today me and my so called fiance (now ex) got into it I got so angry to where I started yelling to the top of my lungs and I have anxiety so I started to get to the point where I couldn't breath it's not the first time this happened but this the first time I got this worked up it was horrible.. Now my feelings hurt and I can't stop crying cause I feel like I hurt my unborn or Put strain on her...

What's the worst that can happen will she come out a still born, born early, or health problems I'm so scared she moves but not as much it would be hour on top of hours I would feel her move and I would get contractions....

HELP PLEASE!!!!!
