Drama (really long) pls help!!!

Friend 1 thinks she is being left out- because we accidentally left here behind when walking cause she was walking slowly due to the heels she was wearing, normally our group walks same speed (when hanging out all night, she still joined in with activities)

Friend 2 is pissed at friend 1 cause she found out that friend 1 thinks they are only friends, because she is sympathetic and hangsout with her cause of me.

Friend 3 and friend 1 has never gotten along. They would verbally abuse eachother lowkey.

Me: found out friend 1 thinks i value friend 3 more than her- so friend 1 is pissed at me. Also friend 1 thinks i blame her for everything even tho i told her it was my fault for leaving her behind when we were walking. Found out that friend 1 has a crush on me and i dont like them.

At the end friend 1 has not responded to any of my or friend 2 text or calls. She has given us all the silent treatment and cold shoulder.

I have given her space a day, idk what i should do cause she has been suicidal and on medication for depression and other stuff. Their parents know the situation, but they still wont talk to anyone.

So wtf am I suppose to do, since everyone has gotten up me for not trying, because honestly this isnt the first time she has done this (but its the biggest). Also does it sound bad if i said i have no fs to give anymore cause im over it.

Pls someone help me!! ( sorry that its a lot of drama)
