Tears flowing nonstop

I'm 7 weeks pregnant. Y'all I cant stop crying. I can't shake the dread feeling. I can't shake the anxiety and I'm borderline full on depressed. I'm afraid to get excited. Afraid to breathe, move, or think. Had a scare the other day, i thought i lost my baby. I was in the ER and every thing. Im also having very vivid nightmares. For example: I was in the bathroom and went pee....when i wiped, there was my baby, in my hand, 10 little fingers, 10 little toes. Completely perfect, just 6 months early. I cried myself awake in that nightmare. I can't sleep. Y'all please tell me I'm not insane. Please tell me yall have this too. I feel like my life is falling apart.
