How to overcome PPA?!

I am calling some therapists tomorrow I was referred too but I just need to vent right now. I was on TikTok and came across a video of a baby who passed away from SIDS. My WORST fear!!!!!! My daughter is 2 months and it literally makes me sick to my stomach thinking about it. I don’t know what I would do if something happened to her. I really don’t. And thinking about it makes my heart race right now. When I wake up in the middle of the night I’m constantly checking on her and I’m super cautious about safe sleep. Is there anything any of you girls have done to help you feel a bit better? I can’t look at her right now without getting upset because of it.

Also, I’m well aware of how I am right now and that’s why I’m going to a therapist!
