Hopefully if you didn't hear anything about the tests it means they were ok. Or at least not terrible. If they meant you needed urgent treatment someone would have contacted you.
And remember, even if they do recommend another colonoscopy you don't have to agree and you don't have to agree immediately. Nobody can force you. I know it's a bit of a catch 22 situation, but you do have choices even if they're not the choices you'd hope for.
I would really recommend asking to see the ibd/ clinical health psychologist - they can be brilliant and really practical. They might have a little bit of a waiting list but if you ask now things can get started.
It might be they could help you look at things that could be done differently by the hospital to support you, especially with any future colonoscopies. It's not supposed to be "this is how we do things, tough luck if that damaged your mental health". Protecting your mental health is important too.
There are things that can be done, although it might be hard right now to imagine what they are.
So even if they say they would like you to have another colonoscopy you can say "I can't cope with that right now, I will need some support to be able to consider that." And then ask for the referral to psychology, do some work with them to build a plan and help you make a decision.
(You might have other priorities. I'm just using this as an example of something causing you a lot of distress right now that they could help with in practical ways.)
Take care
