I am referring to my older sister, of which I am very close to. She is 25, and like me, has had lots of mental trauma from childhood due to our Mother's abusive boyfriend (state declared mentally challenged- abusive physically to her and us, also used any and every drug on a daily basis, stole from us to buy his drugs), our drunk Father who was constantly jumping relationships (and only in the picture when he needed to show off his new family), and sexually abusive uncles (during our toddler years). Over the years, I have noticed that her mentally seems to be slipping. She has had several wrecks and speeding tickets due but not limited too: lack of attention, texting while driving, aggressive driving, and chasing unhealthy relationships. All of which to me seem like a mood disorder, especially since her demeanor can change over simple nonrelavent things. I have asked her several times to have her mentality checked, yet she refuses. There are several other factors that contribute: 1. She has been on muscle relaxers and pain killers every day since her first wreck (8 years ago). 2. She has been on birth control since she was 9, due to unbalanced hormones, even though the birth control doesn't help. 3. I often have to talk to people for her, she can never seem to collect her thoughts correctly and often leaves out important detail/questions when communicating with anyone (doctor, judge, bill collectors, bosses at work etc.) 4. She eats out and shops for unnecessary clothes/items before paying any personal bills (even though she cannot afford household bills or to help) . 5. She has never lived on her own, even when she has had the money to do so. 6. She has poor judgement on guys- (this is just one incident) here recently a guy took her to the middle of nowhere and forced her (threatened if she didn't) even though he had been verbally abusive to her within their first 2 dates and through lots of text messages. 7. I have to ask her to clean her room, or help out with dishes/any house work, even though she lives here and pays no bills (my sister has lived with me shortly I moved out on my own at the age of 17). Expecting her to clean after herself is a joke, even though she is constantly told. 8. She expects hand outs from everyone (work, parents, grandparents, siblings, government etc.) constantly wanting something for nothing. 9. She will not try for any type of physical or constructive activity. 10. Often expects other people to do things for her- the list could go on here. 11. Does things without educating herself first/considering the consequences (She drained $16,xxx from her Stocks and 401k this past summer while receiving full unemployment benefits of $245 a week from a plant shutdown, and spent it all shopping, eating out, and some went toward her car. She never put any back for tax penalties, rainy day, or for her to be on her own!) 12. Seems to want to fix everything with her pills, and not try to fix her problems so she can be independent. 13. She would rather take advice on what sounds convenient for her, instead of what is best for her. 14. When she is caught being dishonest, she lies and gets mad to cover it up. 15. She is constantly seeing married men (same men, weekly basis), and is constantly personally meeting new guys on Craigslist without telling anyone where she is going or who with, despite previous safety issues/abusive encounters. 16. Says random off topic things when trying to get in on a conversation. I am about the only person she talks to, but she will not consider any of my advice for mental health treatment. But at the same time, I do not appreciate her lifestyle or the influence it can have on my son. Even if I tried to give her the boot, she would just go back to my Mom's house and start complaining about her horrible life there. I am not sure what to say or do anymore. Note: She has only been on the birth control since she was 9 for her unbalanced hormones. The prescription pain pills have been prescribed by a doctor due to inflammation under her skull and in her upper back from her 3 major car wrecks.
