Sweetie pie! I only just read your post - what a lot of cr*p you are going through. I agree with the others... when you've got a bit settled in Canada I think you need to find a counseller and get some better a-d's! Those thoughts aren't nice - I've been there way too many times and I never want to feel like that again.
I've had the throat thing too. Only once majorly, but then I thought I was gonna die. I think the IBS/nausea stuff can trigger that off and then the panic makes it worse. For me it was like I had gas trapped in my throat when we were on a plane that was landing (in Denver(!), so my pressure sensors were totally messed up!). I felt I couldn't breathe - I was gasping and not getting air. It was so so horrible. I REALLY feel for you if you're getting them alot!!!!!
You are NOT crazy. I think alot of us have been there. All these illnesses and problems we get landed with are a bit much. Btw - sympathy on the boyfriend front! Simon gets a bit like that too. I reckon it's a man thing. Drat them!
Hopefully, leavingthe mad-house and getting back to Canada will help, but get some professional help as well, okay?
