Sweetie, NO-ONE is expecting you to just get over your loss like that! You are being totally normal. Go hide under the duvet and scream and cry if you want to (hitting pillows sometimes helps too ). Totally normal. Can you call the docs and ask them to call your mobile if the doc is running behind-time so you don't have to be in the waiting room for any longer than you have to be? That has got to suck BIG-TIME.
If it's okay with you, I'll ask a wonderful woman called Cath from BYDLS to email you. She's in her fifties now and has Lupus and all sorts of CTD stuff. She was really ill when she had her 2 kids as she wasn't diagnosed till recently but she coped! She's an amazing woman. Us Spoonies (chronic debilitating illness sufferers) have ALOT to look forward to in life and all this cr*p can help us become even better people and make amazing friends. So do not despair sweetheart!
PS. Could you print out your "fury" posts and take them to your shrink? Or just make notes in between sessions of stuff you think of? If I don't make notes I never remember all the stuff I want to bring up.
