Going through a tough time right now!!

Well, let me start this post with the past. 19 years ago my roommates wife and him ended their marriage.  His ex- wife did everything she could to keep him from being a part of his daughter's (and later a son's) life.  So his son never had the opportunity to have a relationship with his Dad, and the first 2 years of his daughter's life...well she was way to young to remember the "good days".

Fast forward to approximately to April of this year (the year after his kids mom passed away)...his daughter was trying to help her brother out as he had no place to live and asked her Dad if his son could come out to our city to start his life over again.  Of course my roommate said yes that he would like nothing more than to get to know his Dad.  In July, his daughter followed her brother to our city, and realized how irresponsible he was a that he spent her half of the rent that she gave him and so my roommate felt bad for her and asked her to come and live with us.  The deal was that she would be able to live here "rent-free" so long as she put in an effort to get to know her Dad.  From about the middle of August until last night she lived at our house rent free and she DIDN'T even have to buy much food unless she wanted something special for herself.  She never tried to have a relationship with her Dad and stayed in her room most nights when she wasn't working.  Now we know that she might have different interests from what me and my roommate like to watch...but all she had to do was to ask if we wouldn't mind watching something she wanted to watch, and we wouldn't have had a problem with it.  However, she told my roommate that she would rather "stream" the movies and TV shows she likes to watch, so effectively keeping her in her bedroom.  She also asked if we could up the amount of data that we are allowed with our current cable plan. Even when i went to great lengths to make a nice ham dinner for all of us, she just made herself a plate and took it to eat all alone in her bedroom.  She also asked my roommate if she could have a"friend" over to "hang out", and they did so even though she knew how uncomfortable it made my roommate, especially when we could tell that the lights were all shut off in her room when she had her "friend" over.  She was also very Moody, and I'm pretty sure she was out of the anti-depression pills that she was taking.  The only time that she would talk to us was when she wanted something.....like to go grocery shopping....stuff like that.  Since she was NOT making any effort to get to know her Dad he confronted her and asked her what her plans were and she stated that she would be looking for a new place to live, by herself by JANUARY 2018.  My roommate decided to teach her a lesson and cut off her WIFI access last night.  After he did that she comes stomping out of her room stating that she wasn't getting any WIFI access and when she asked me to call the cable company (NOT POLITELY AT ALL) I told her I would call the cable company in the morning, but that wasn't good enough for her and so she called me an "F-ing c*nt".  I texted my roommate because i thought that that kind of language was very crass and disrespectful.  My roommate who was on his way to the movie theater came home and ordered her to leave the house, because of what she called me.  She eventually left the house after we called the cops on her because she wouldn't leave!!  We packed up all of her stuff and found a large amount of Gatorade bottles (that we buy for my roommates lunch aswell as various plates and bowls from all the food she was eating in her room.  She even had me hoarding food in our bedroom....otherwise I wouldn't see the boxes of crackers and chips that we had bought until it was all gone..

So my roommates, sister comes over to the house with my roommates daughter and a police officer to act as a mediator while she was picking up the rest of her clothes and stuff from our house.

So here i am really stresseed out and barely able to keep myself sane.  Part off me wants to end my life, bit i don't know how my roommate would feel as this was his "daughter" who brought all of this on herself.

HELP I NEED YOU GUYS TO HELP ME OUT HERE....PLEASE LET ME KNOW THAT SOMEBODY CARES ABOUT ME!!
