Thanks so much for all the replies! They've helped a lot and reduced some of the anxiety I was feeling.

I think now that I did interpret things in a distorted way and I'm so glad I didn't react in the moment. Not reacting causes a massive surge in anxiety but I think I'm learning that it's best to try and resolve that later, at a safe distance, rather than in an angry outburst which can leave everybody hurt and confused (including me). It's difficult but being able to post on here and get advice from others who've been in similar situations really helps.

I'll see how it goes next week and try to remember to hold back and not act if my feelings start to overwhelm me.
