i have this friend with me who is depressed but he/she/they is/are toxic and very sensitive like last time when they are in their sad time and I didn't text them back, they started going crazy and telling me that I was not a true friend... if i stop being friends with them i am worried that they will kill themselves because of me

You should tell someone about this before it's too late.

Tell an adult. Your parents. Or teachers.

So what if you betray them and they hate you because you told them?

You'll save their life, that's all that matters.

Do everything you can to convince them.

As long as you safe their life, everything should be alright.
