29 weeks pregnant and completely overwhelmed!?

only 11 weeks to go and im cacking myself! worryin so much about money as my job ended and i have to sort out income support and hate the idea of bein stuck on benefits tearing my hair out coz i hav nothing to do til baby comes, worrying about coping when he does arrive (partners ex had postnatal depression n his daughter- 20 months- lives wit us full time because of this), worryin he'll take him away if i make a mistake, worrying about names etc. its a nightmare! every twinge or somehting makes me think somethings going wrong! sorry bout long question i'm just completely out of my depth! did anyone else ever feel like this?
