Miserable since bfp

I'm only 5 weeks but I found my bfp really early. I'm sorry to say I'm miserable. Most women have a 25% chance of miscarriage, and that's how much a chance I have of keeping a full term pregnancy. I keep getting pregnant and having early miscarriages and I thought I wanted to keep trying but this stress of waiting to miscarry yet again is killing me. I would have scoffed and wanted to slap a woman up and down before this began if she acted like I am now. I would have been so jealous she was actually pregnant and mad she was taking advantage of it.

How do I try to be happy with what I have right now? I'm hormonal and miserable and pissed!
