I can't stand my friends anymore

I'm done with them never paying any attention to me and faking to be interested in my life. I might only have 2 friends that actually care about how I'm doing but apart from that I've only received judgment and neglect from most.

I used to have a somewhat big friend group (actually, I still do, but I don't feel close anymore) and I had someone that I considered my best friend. However, this past few weeks she has been hanging out with a childhood friend of mine, without me, talking bad about me but then when she sees me she acts like nothing happened.

I know all of this because I've been told by other people, who won't even defend me when other people talk shit about me. One of my "closest" friends even told me that friends from her college (whom I've never even met) tell her to stop being my friend, so when I asked her what she was telling them she wouldn't say anything.

I'm done with this, everyone is a hypocrite and can't even tell me what they're bothered by to my face. I feel so alone lately because I don't think I can't even trust anyone.
