So I'm 13 years old and in 7th grade. I have this friend that I met this year. She's been a really good friend to me but I wouldn't describe her a best friend. There has recently been some drama over someone liking her and she lashed out at that person in a group text I was in, using extreme expletives. I texted her about it and asked what was up, and she said this:
The reason I yell and lash out all the time is because I am constantly sad. I'm lonely. Even when surrounded by a lot of friends I still feel alone all the time.
I'm sorry I shouldn't have told you all of that. I'm going to go, bye.
And dont think about it. I'm fine don't worry I won't do anything.
I'm sorry.
Sorry.
I've been as supportive as possible but as she opens up to me more and more it seems more like she needs to tell someone who can help her about it. From what she's told me, I have a suspicion she is bipolar. I've encouraged her to go to a doctor or to our guidance counselor, but she says that she 'can't trust them' and that the doctor would recommend pills which would 'screw her up even more'. She has told me she doesn't want me to tell anyone about it, and I said that I would only tell an adult who can help if I think she needs it, but I if I did she would never forgive me.
What can I do about this? What can I say, and should I tell her parents? I want to help her, but this is scary to me. If any more info is needed, feel free to ask in the comments.
Sorry if this is off topic, as it isn't a question directly about parenting, but it seems to be on topic from what I have read on meta.
