My friend opened up to me but i dont know whats wrong with her😰😰😰

She admitted to me a few weeks back while intoxicated that she made up about her dad sexually abusing her and doesnt care because "he deserves it" for battering and raping her mum and other women. Even still, its wrong, why not just let karma get him!! 

She makes up permanent lies and actually believes them, then confides in me with worry that they werent true, followed by asking repeatedly "what is wrong with me T". Shes hypersensitive to EVERYTHING. U say "aw im fed up with this day" she says "omg is it me what have i said what have i done ive pissed u off havent i?????" And i get harassed. She is told of something horrific and she laughs her head off!!! She is also a theif, she steals from best friends, family and the public and does not care aslong as she isnt caught. She has serious depression and extremely bad anxiety issues and was neglected by her mother and father. 

I know in my heart theres something not right with my friend, these things worry me but i cant quite put my finger on what it is im dealing with here. Can anyone PLEASE enlighten me what could be wrong with her😩😩😩
