Not shure if it's from the exostion

So my tia and I had a falling out over bump pictures when I was 16 weeks pregnant (36 now). But I was so scared of having a miscarriage I didn't want to take any pictures. I was even too scared to go to my appointments. Until I was 24 weeks. So anyway we had a falling out and i haven't called her since i dont think i have the balls. Or the courage so I send her emails and text message most of the time I get things like k or that's good. It feels like she doesn't care anymore and I wasn't even the one to say anything mean all I did was say I didn't want to take bump pictures I didn't explain why I didn't. Probably should have. My husband got mad when I got stressed out and started crying I wasn't crying over the fight I was having with my tia I knew if I left it alone long enough she would stop asking I was crying because I am a cna and I lost a patient that day I watched him die like I watched my dad and Agian I couldn't do anything about it so that is why I was upset and crying. But my husband thought it was my tia and he went off on her. Now she wont talk to me. She was my rock for so long and now that my due date is getting closer I am getting more and more scared of something going wrong normally when I was this scared I would turn t ok my husband but he is always working and I don't want to stress him out. So I want to call my tia because she is like the mom I never had but I am so scared that she is going to tell me to f off and never call her again. I cant stop crying and beating myself up over what happened that night and I just miss her so much. I am such a coward.
