anxiety problem...

Caity
Hello, 
Hoping some of you can reassure me, I've tried counselling and speaking to friends and family and nothing works, I'm almost 13 weeks and I feel like I'm having a total meltdown, I've just sorta realised I have to give birth to my baby!! My worst anxiety problems are dying- to me I am worried I die giving birth or have to get a c section and something goes wrong etc (this is serious btw) and I am just terrified , so worried to carry this baby incase I hurt it or if something goes wrong during labour I can't stop it! How an earth do you get past this feeling is there groups (uk) or anything that can help me? I can't relax it's all I think about and I will harm my baby :( any advise is appreciated. X
