Please help! I'm desperate.

I keep getting intrusive thoughts about EVERYTHING. Anything can trigger them. I hate myself and wonder why I'm even on this earth if this is what I have to live with constantly. I'm sick of these intruding my peace. It can be anything, something sexual, something violent, something scary. Anything. It triggers my intrusive thoughts. They've never been this bad, but being pregnant has ruined my mind I almost feel like. I still am self aware and know I would NEVER do any of the intrusive thoughts, I just don't know how to prevent them.

I know it only makes it worse when you try to block them out, but I can't just sit and try to wait them out. My mind immediately tries to force the thoughts out. How do I overcome this? I'm so scared of it getting worse after the baby is born. I can't live like this anymore.
