Hi russlac
and welcome fellow Brit
where are you?
sorry you're having such a bad time, but cos you're in the UK, you have the right to choose your own hospital, not just the one your GP recommends! If you're not happy, then find a new gastro and get a second opinion, don't just give up on the say so of one doc who sounds like she doesn't give a flying F***! Try another town for example.
I understand your anger, fear, disbelief, confusion etc, so first of all, chillax!
have a scoot round the forum on the low residue diet, this consists of eating no fibre, just plain simple food, chicken, white rice, white bread, fish, potatoes, no coloured food, for starters, it's not just bananas! keep a food journal, it's a process of elimination, if it irritates, don't eat it again, then slowly reintroduce it back, this will become manageable as time goes on, I promise! I eat steak, but can't tolerate Chinese!
I see you're on Pred? give it time, it does work wonders, and did your doc mention Calcium supps to take with the Pred? if not, you need to ask about this, cos Pred can rob you of your calcium, any questions, fire away, we're Pred experts!
lots of support here, you're not alone with this, take care
lotsa luv
