Struggling after miscarriage

I’m not really sure where to start. I miscarried at 7 weeks (1.5 weeks ago) and am really struggling.

I feel so despondent and disconnected. The guilt is overwhelming - did I do something to cause this? Was it the heavy bag I lifted? The hours on my feet? The hot bath I took before I knew I was pregnant?

It wasn’t a planned pregnancy and my partner did not want to have a second child - I had been ambivalent, but the pregnancy made me realize it was something I do in fact want. This compounds the grief, because I feel like there is no hope of trying again - it’s a really desperate feeling.

It’s hard to even be in my body right now, because the loss of pregnancy symptoms feels like a perpetual trigger.

I am also feeling like a terrible mom, because I can’t be present with my little guy (3 yo). I don’t want him to worry about me or to feel left behind. He is my world and I love my family, but I’m really struggling to feel connected right now.

Does this get better?
