30 weeks pregnant and depressed

Is anyone else struggling with third trimester depression?

Today especially, the littlest argument my husband and I had led to many tears and exhaustion. Lately I have been feeling so alone and depressed and ugly and i feel like I'm an annoyance to everyone. I have this deep sadness like I'm stuck in darkness alone and if i were to scream, noone would hear me.

I feel guilty because I'm scared to have my son. I don't feel like I'll be a good mom to him.
