So... I just wrote a long reply... and it vanished... FUMING!!!
I understand what you're going through 100% because I too have fibromyalgia. Its tough, its cruddy and do you know what? Its totally okay to feel how you're feeling.
It sounds to me as though you are in the same prediciament i was 6 months ago. My doctor was (unknown to me at the time) useless at dealing with fibro, and randomly my doctor went away on holiday so I had to see someone else... who was like a breath of fresh air. there was understanding and support and for the first time ever... i didnt feel i was wasting someones time. Do you know what i mean?
I have a blog - fibrowhat.tumblr.com.
I'm also on twitter @slooong
im here and i care.. even if you just want to moan and cry
there is a great NHS hospital in london that deals with fibromyalgia and can make some minor edits and changes to medication that can make a huge difference. (www.fmsclinic.co.uk
If you haven't already CBT training can make a huge difference. Keep harrasing your doctor until you get it. You are entitled to it.
Rememeber the more you dwell on how ill we are (and you are quite within your rights to do so) you run the risk of bringing yourself down. These days rather than looking at what im not able to do... i focus on the achievements ive made that day that i wouldnt have been able to do say 6 months ago. Yesterday I was able to do a full day at work. And for me? That was a huge step.
Remember ending it all, whilst at the time you feel it might be justified, its a permement end to a tempory, although chronic problem.
I beg of you.... please get in contact, there is help out there for you.. and i care. i promise you... I REALLY CARE ABOUT YOU. Your a fellow spoonie (google spoon theory) and we gotta stick together.
`It gets better' may be overused..but hun, its true
IM HERE - WORLDS HUGEST HUG.
