Paranoid intrusive thoughts about my daughter

My daughters almost 2 years old and I’ve always been paranoid of something happening to her but lately it’s getting out of control. I have random intrusive thoughts or images of horrible things happening to her. My biggest fear is something happening to her. I guess that’s why it keeps coming into my head but I isish it would stop. It’s destroying my life and my sanity. I am on medication for bipolar depression which is supposed to help and have an appt to start seeing a therapist but Idk. The only times I DONT have these thoughts are when I’m with her, but unfortunately her dad and I split up so he sees her half the week and I just suffer. I need help. I can’t deal with this
