I am writing because I am worried about my roomate.She is prescribed to 100mgs of adderall a day (which I think is way too much) and still runs about 2 weeks after she gets her prescription.The days after she gets her prescirpiton filled she doesnt sleep (when she does its usually for no longer than 2 hrs.).Even though she doesnt have a heavy schedule in school this semeser she stays up day and night in her room working on things and has stopped going out on the weekends completely (even though thats something she used to love to do and talks about never having fun).When she runs out she'll make up some story about giving some away or something else that doesn't make any sense so that she can borrow some from a friend.When she runs out of what she borrowed she'll keep baggering ppl for more until they have to firmly say no.When she cant get anymore she'll go to sleep early (around 10 pm) but wont get up until 1 or 2pm the next day.When she does get up she spends the majority of the day in bed.Her mood swings have been problematic for our relationship.When she's out of adderall she's social,but when she gets more I rarely see her leave her room unless she's going to smoke.Her behavior has become erratic, she'll talk about random things and switch topics often.Whenever I try to talk she interrupts me and starts talking about something entirely different.When i ask her to let me finish and then ask her opinion about what i said,she'll laugh and ask me to repeat b/c she wasnt paying attn.She'll go off on tangents about how the world is ending and is convinced that she knows everything even when she's saying something that is clearly untrue.When I attempt to correct her she talks to me in a very condescending manner, so I'll just walk away.And she will go from not talking to me to asking me if i'm ok repeatedly.Her behavior has gotten incredibly erratic and paranoid.She has been constantly ranting about how ppl are out to get her after she had a dream that her friend was trying to kill her.Her thoughts are very unorganized and she'll be worked up over something and look terrified and pale but wont be able to explain why in a way that is understandable, she'll just say someone's otu to get her.She's incredibly inconsiderate and makes loud noises all night,always piles her dishes in the sink and leaves them in there for days (they'll stay there a week if you dont ask her to clean them),and says rude things without thinking about how they sound to other ppl.To my understanding adderall is supposed to make a person more focused and driven,but she doesnt follow through on anything she says shes going to do.She hasnt had a job in 2 yrs and is constantly changing her career path (she's in grad school for something she hates and decided to do somethign completely different but is staying in this program).She never takes responsiblity for things, there's always some rationalization or excuse.I'm really concerned b/c she is very petite, 5' and under 90 pounds which is weird considering she's 27.I know some ppl are naturally thin,but this is unnatural. she has no body fat whatsoever, no breasts, no butt, and she wears a sz 12 in childrens jeans (and still wears sweatpants under those to appear bigger).I never see her eat meals, just snacking on yogart or fruit and drinking coffee.She smokes alot also.I was wondering if any of these symptoms sound familiar to anyone b/c I am worried about her.I care about her and know she's a good person, but her personality has completely changed from when I met her.Her symptoms appear to be bipolar or schizophernia, but I have a feeling its the amount of adderall she's taking.I am in therapy and I suggested she start going, but she told me that she doesnt need it.If anyone has any advice I'd really appreciate it!
