I don't know what to do

My friends have cut me off. I don't know what to do.

When I ask to go out for drinks I don't get answers, and when I do I get answers I'm then told it's called off at the last minute even though I know it isn't, they're just going out with her instead.

I know it's my fault, I couldn't get over her fast enough. I talked about how I felt with them. They decided I'm being toxic, that I'm being obsessive about it, that I'm having a stereotypically masculine angry reaction to what happened.

I feel like I should just leave all the groupchats, block everyone, abandon all the years of friendship I've built with them, all because I did not like being tossed aside for another guy when she and I were talking about becoming official, and actually be in a reliationship.

I hate this so fucking much, they're all the friends I have and I lost all of them, I lost fucking everything because of this fucking breakup I don't know what to do anymore
