Best friend or not best friend?

[ToastBandito]

This girl, Raven, was my best friend for my entire freshman year. I was always there for her when she was down and she always gave me a good laugh. Recently, she's been acting different towards me; and not in the good way.
She's always lashing out at me and getting angry at me for no reason. I'm really confused. She yells at me for not helping her but she never tells me her problems and covers it up when shes upset. She lies a lot about her life: both good and bad. What she does and who she is are two different things. She's nice to people who aren't as close to her as I am but when she's around me she screams at me.
Tonight, I was at a funeral for a favourite desceased teacher and she comes up crying. I'm currantly trying to help all these other people and I try to help her but am dragged away. Then I hear that he's gonna curse me out the next day. I didn't understand why so i asked her about it and she huffed and said, "Like you would understand." I broke down in tears because I'm really confused as to why she's acting this way. Two girls tried to make us make up but we just got into a bigger fight and almost started a yelling match. All my friends told me she wasn't worth it, I still felt sad cause all I want is for people to be happy. I've been crying for the past three hours wondering what I did wrong.
Please help me!:(

maybe you should just confront her about it but do it calmly like "what is your deal? your always mad at me for no reason". She might be having problems at home or something but its too personal to talk to someone about it. idk but good luck, i hope it works out for the best

Try talking to her in a calm manner, don't get harsh, and if she does, just let it fly off. Somethings obviously upset her, and as her friend you should help her.

See, I've treally tried to be there through everything and I always use a soft calm voice when speaking but it doesnt matter what i do because she ends up screaming at me.

It sounds as though she’s got something on her mind that she either needs to just let go off, or she needs to resolve it and move on. Maybe if you can get her to talk to you without being defensive perhaps she has issues going on at home that’s hard for her to deal with. If she’s not willing to talk to you in person maybe you can try passing her a note explaining your concern for her. You might also mention that you miss her and you don’t want the friendship to end. Let her know that she means a lot to you and if she needs to talk you’re willing to listen.

You don’t want to seem pushy and force her to be on the defensive because she will never open up to you. Maybe she’s had a talk with someone else that can help you get to her. If that doesn’t seem to be an option and she’s not willing to talk to you then don’t push it, back off a little and give her time and space. It may not be what you want but it just might be what she needs. Unfortunately she’s the only one who can give you the answers in which you seek.

This may be bi-polar disorder. She seems to be lashing out at random times, creating lies about her life, and she seems confused. Compulsive lying may be another contributer, but I am not good with mental disabilities.

Confront her, or someone closer to her than you like her parents. See if they have an explanation of why she's lashing out randomly, and if it's only towards you, you should maybe learn to move on. Friends come and go, a sad part of life, but learning how to look past that and find new friends can make you a stronger person.
