One of my friends (M)

Tried to commit suicide because he is obsessed with my other friend (T) but T wants nothing to do with him. Rightfully so, they were just friends and M got all weird and obsessed over him. So one night at the bar a few weeks ago T was kind of like shrugging him off and ignoring him all night which sent M into a spiral. M went missing all that weekend and i was so fucking worried sick. We finally got ahold of him not until that monday morning though. He is still hung up on T but I'm like you cannot force people to be your friend!!! I took him to the movies and stuff but now whenever we are at the bar I have to bounce back and forth between M and T and it is so awkward and M always has like a fit at the end of the night. UGH EDIT: It is a known thing that M will fake having psychiatric fits over things like this but I am afraid one of these times it will be real. I was warned to stay away from M just incase I get roped into this and that it isn't fair i have to deal with someone who uses suicide as almost a threat but ugh its just hard because M has mental disabilities and I don't want to just abandon him
