My cousin is a few years older than me (60s) and we normally have a good friendship and are going on a holiday of a lifetime in a few weeks. However I have been going through severe anxiety recently due to having trauma therapy which has triggered a few things (nothing to do with her). She always insists on facetiming but for some strange reason I can't do this as it makes me super anxious so I've voicenoted her explaining why. She has replied by text saying to "fucking" ring her then as voicenoting isn't good enough. This has now made me super anxious because I know if I call her she will have a complete go at me. I've had 6 weeks of sleeping no more than 2 or 3 hours due to the therapy and now I know the anticipation of ringing her will add to my sleepless nights. I only have another 4 sessions of therapy and I know things get worse before they get better so I'm not worried about that per se. But with my cousin it's getting to the point of saying I don't want to go away with you as I feel bullied. Am I being oversensitive over the facetime/call thing?
