Scared if I don't stop something will happen to the baby

I cry every night I can't help it. I'm scared that my overwhelming feelings of sadness and stressing out over the loss of my mom back in April will result in something happening during my pregnancy.  I am 10 weeks pregnant and it's so so soon after her death that I haven't even processed her being gone .... Now her not being here for this is hurting so bad. ❓Can this harm the baby? Or is crying ok?❓ Silly post I guess but I'm always up late crying thinking of her:/ I didn't think this would be so hard
