I desperately need advice...

I'm 8 months PP. I've always been an anxious person but lately my anxiety has been crippling. I feel like I'm not in control of anything anymore. Not my emotions or thoughts. I feel like I'm constantly racing. I have a hard time sleeping. I'm always worrying to death about things that haven't even happened yet or might not even happen but I worry myself sick.  I'm not depressed and I'm still feeling happy until something stresses me out and I just can't cope. Is this normal? I really don't know. I'm too embarrassed to talk to someone because I feel like they will think I'm just looking for attention. Will this just go away? I'm having a hard time.
