How do I deal with this girl, she has several mental disorders

I think I am certain this has never been asked here before, but hey, I do not know for sure. Let’s start by identifying the current problem I have that nobody has found a satisfying solution for. I made a mistake– I was in a time of desperation and loneliness and met a certain girl on MySpace. To make things anonymous I will refer to her as Ms. L. Ms. L’s personality appealed to me like no other, she knew things that I knew that hardly anyone else knew and she understood and conceived things that I did without problem! Too good to be true, she is also very attractive.

Her being my siren, I was lured into my own personal, daily nightmare as of today. Everything seemed to be running smoothly so far for a long distance relationship; distance was never a factor to us, I talked to her on web camera and phone every day. Until one day the first pothole in the road appeared. She introduced a certain twin brother, he was very perverse and forward in nature. (He also claimed to be homosexual) And he claimed to harbor an attraction to me. This did not make me happy but I decided to condone it.

The brother “grabbed” the phone very often. Take note, as this will mainly give you the idea of what’s missing here.

1. I never heard footsteps, background voices, or hands grabbing at the telephone.
2. Ms. L and her brother had voices that vaguely sounded similar.
3. In photos of her brother, I noticed a just a touch of femininity in the face, and that the chest was always hidden in the picture.

Finally one night my suspicions were confirmed. She has Multiple Personality Disorder. Followed by DID, ADHD, ADD, Manic Depression Disorder, and constant suicidal thoughts.

Like so many relationships, when I gave hints on my breakup, she threatened to overdose on pills because I was her only reason for life.

Trapped. Hopeless. Scared.

I can’t take it to any professionals seeing as my mother and me are not very abundant in finances.

I have asked this question for months… I’m here now asking again. Still not giving up. I want to be happy again, go back to things before! Without her taking a dozen pills like a foolish person.

Has anyone any advice to offer to end this so I can keep myself from going insane?
