Firstly you seem to have identified the problem, don’t underestimate how difficult that can be to do! You have asked for a change, also big tick, that leaves you with management of the current situation so it is at least bearable, a trip to the GP would be a good idea, also google iapt in your area as they are often self referral and will run short course cbt/mindfulness type stuff which will give you some more tools in the box. In the meantime I’d suggest the mindfulness book by mark Williams.

Have you struggled before or is this a new thing, it can be a bit scary either way but also we can’t expect all situations to suit us :), I’m awful a lot of the time but love being left here on my own, it’s quiet and I can just get on.
