I think I'm getting tired of my friends

On New Year me and two other friends (let's call them friend A and friend B) confronted our friend C about the fact, that it seemed like she was avoiding us. Turns out it was the truth - some of our jokes were making her uncomfortable, but she didn't know how to tell us that. At the time I didn't think much of that, we just promised not to make jokes like that when she's around and everything returned, more or less, to being normal.

Now few months have passed and I see more and more what she meant. I meet up with friend A and B this weekend and it just been... weird. First day was cool - we were getting ready for a concert together and afterwards grabbed a few drinks. But there were two more days of our time together and these weren't so nice.

Most of the time I was just counting down to a moment I'll be back home. And I did try to point out that some of the things they said made me uncomfortable (maybe in not serious enough tone, I don't know) - but all they said was either "womp womp" or "you're overreacting". At the last day they just unlocked my phone and used it while I was in the bathroom, despite me explicitly saying I don't want them to do that (previous day they did the same with my tablet and then promised not to do that again, yea promise my ass).

The more I think about it, the more situations like this I remember. I don't want to cut them out off my life, but every time I tried to tell them I feel uncomfortable they treated it like a joke. We went through a lot together and, to be honest, I don't have any other friends. Sure, there is friend C, but I don't really talk with here on priv, and one person I met on here, but I don't know them long enough to consider them my close friend.

And I'm not sure if I could even leave them without feeling guilty - one of them strongly reacts to everyone who drops contact with her, the other one is currently in such deep depression, I'm scared that she'd do something very stupid.

I just don't know what is worse - possible loneliness or current discomfort.
