Friendship Betrayal: Refusing to Help After Wishing Me Dead

very long story So this girl let's call her K(29F) has been my(18F) best friend for almost 2 years I was the maid of honor at her wedding I am also currently living with her brother let's call him DS(30M) he's my bestest friend in the world and I still care about K very deeply This story starts with me watching K and her husband's house and animals while they were at work in exchange for $100 every 2 weeks I stayed a total of 3 weeks and 2 days I have severe separation anxiety and being away from DS and my ESA's for that long took its toll on me and because of the depression that was a symptom of my separation anxiety and a few other reasons unrelated I attempted to take my own life off their property but was picked up by ambulance on their property I got a friend to watch their house and animals and that wasn't an issue but I ended up thinking myself down and just spent a night in the hospital and went back to their house to finish my stay when I got out while I was in he hospital the dog hadn't been let out and time and pooped in their room which I refuse to enter when they are not home so I had no idea When they come home like 2 days later it was really late so we agreed I would come back the next day to collect my pay and cook them my special fried chicken recipe I left as soon as they got home and had walked about half way home (about half a mile) when they called me over the phone about the dog shit in their room demanding I come back and clean it up or I wouldn't get paid so I walked back to clean it up just to get there and be immediately told to leave their house I would not be getting paid the $150 they owed me and (I desperately needed) and that I was now blocked on all social media I turned right around and left then walked the mile to get home just to find a text on my phone demanding I pay them more then $200 so they could get a cleaning company to come clean their entire house because their saying "I destroyed their house and left it an absolute disaster" just to be absolutely clear K and her husband are absolut slobs that refuse to clean up after themselves they have had 3 live in maids that quit because of the work load and because K's husband is a straight dick when you are in his house his word is law and if you don't do what he tells you to he will force you to leave I refused to pay them the money I absolutely didn't have because I am out of work due to a PTSD attack and even got 3 people who were witnesses (including DS) to their house being a total mess when they left and that when I left it was picked up and cleaned up a bit and in much better condition then what they left it in This all stated they got an eviction notice from their landlord I saw the paperwork it stated that they were being evicted for having other people other then them staying with them and because of the use of illegal drugs Being the 3 maids and K's husband smokes herb they are now saying to anyone who will listen that its because of the night I went to the hospital and want me to pay them $700 because "it's my fault their getting kicked out" Important information me and DS own a truck together my names on the title and his is on he regeneration it is currently needing repairs that are being done this Monday and then it will be running perfectly also this truck has been in my life since I was ten my stepmother agreed to sell it to me for $200 that I'm still paying off the agreement for me to get this truck was that 1 the title could only be in my name 2 it cannot be driven without registration and insurance and 3 that it was not to go anywhere without me either driving or being in the passenger seat But tonight DS was on the phone with K and her husband talking about what to do DS is going to let them live in his camper and help them pay for a storage unit for their stuff they were talking about how it was "my fault" and an ambulance went by our house and K said that it was probably another ambulance coming to get me for attempting to take my life again she then proceeded (knowing I was in the same room and could hear her) to say that she hopes I succeed in taking my own life DS and K's husband immediately told her that she should never say something like that and that it was not ok Conversation continues and DS says when our truck is up and running he would use it to help them move their stuff I immediately whispered that I absolutely would not be allowing my truck to be used to help them in any way I 100% will help them find someone else with a truck to help them but it would not be my truck DS got mad because Ks his sister and "family helps family" but I still refused and now he's upset with me So yeah Am I in the wrong for refusing to let my roommate use my truck to help his sister who said she hoped I took my own life
