I have also found this. I have read this in articles. It doesn’t make much sense to me though- how can things that didn’t bother me in the past now make me really angry? It makes me think that part of the condition is mental rather than something I can’t help?
I’ve not found medication to make things worse, but being stressed definitely makes things worse as it feels like I notice every little noise and the whole world is collapsing on me. I’m sat here now listening to someone playing loud music, and it is making me more and more irritated at other things that wouldn’t normally bother me.
