I agree with everything said so far but can't really advise on the lifestyle stuff as I'm trying to sort mine out anyway . I just wanted to see if I could help re: the IBS. I've suffered with this for 11 years but it's much more under control now (dr's didn't really know anything about IBS when I first had it). I used to get it really really bad when I was a teenager and would be rolling around the floor in agony and my mum felt helpless. HOWEVER, once I found out what it was a couple of years later, the pain reduced to a more bearable discomfort - I swear a lot of it was made worse because I was worried what was happening to me as no one had heard of it.
I found colpermin capsules helped, presume dr has tried you on something like this? (pure peppermint oil in a capsule)
I also think I'm better because I (usually) try and air my problems more these days (feeling low, stressed etc etc) rather than bottle them all up. I've had councelling since, as I was a bit f'd up when I first had it, and I just think you need to talk to people, even if it's just on here!
I got my first bout of IBS again last month after a long time with no problems. This is due to a horrible Christmas (dh lost job etc) and a lot of worry on my mind. Well, even though I was feeling better, a couple of weeks after my REALLY stressful time, the pain came back. I was so annoyed at myself for getting so tense about things as I should know better by now but hey, we're only human aren't we!
I reckon you need to drag yourself down the gym if you know you'll enjoy it. You need to do something to stop yourself getting so worked up!
Don't really know what to say but feel free to CAT me if you want any more info on the IBS (although the dr's are better now so you probably know it all now)
Hope you feel better soon
