Thank you so much for all your kind responses – I’ll reply more fully a little later on

Going back to my friends all meeting up without inviting me recently – I wondered if I should confront them and tell them that it really hurt my feelings not to have been included? Or should I just let it go? We hadn’t been in contact for a while since I left University, but recently I reached out to all of them to explain a bit about what had been going on and that the fact that I was distant in uni was due to the fact that I was at the time coping with depression and anxiety. I thought we had made some progress, so this incident has knocked me back! Do I tell them this is how I feel, or just accept they’re no longer my friends and let it go?
