Depressed in Early pregnancy

I'm 5 weeks and 1 day pregnant and after two miscarriages I should be so happy that I'm pregnant again and yet I'm depressed and I don't know what to do I feel like crying every second of the day because I feel like I'm going to start cramping and bleeding and lose this one too I don't know what to do with myself I don't want to be around anybody and I can't go 30 minutes without crying crying over anyting and It all leads back to the same thing is there any thing that I can do to stop this depression that has come over my body and mind.. I just don't want to end up in the ER I can't handle another miscarriage I'm already depressed and I feel like it's affecting my pregnancy in a negative way.
