I'm new here. I've been reading other post and it sounds as though many of you know way more than me. I've never posted anywhere before and feel so alone. My 22 year old son has something bad going on. I sent him to college a normal healthy smart young man and now he is absolutely crazy and looks like death. I recently took him to a psychiatrist and he was diagnosed with bipolar 2 disorder but that's just difficult for me to believe. He was prescribed medication which he lies and says he takes but he doesn't , I found the prescriptions that he didn't even get filled. He has a serious girlfriend that he breaks up with and fights with constantly so I thought maybe that could be a lot of his problems. It's the first serious girlfriend he has ever had. I have suspected drugs and even went to see a therapist that specializes in drug abuse trying to figure out if it's drugs or a mental issue or both but they couldn't help me much. So this is the situation, he lives with his girlfriend, my mother and I help him financially with rent, phone, cable, Internet, and car insurance, he is no longer in school because he went from making straight A's to failing 2 semesters and he blames me for that because I accused him of drug use. He also drives a car that is in my name and my husband (his stepdad) insists that I get the car out of my name, he would never be able to afford insurance . His only bill is $175 for rent each month, he doesn't ask me for money but we are basically paying for everything. He is very thin, lost all muscle tone, pale as a ghost, and overall doesn't seem clean. He doesn't act like he is on anything when I see him though. He works delivering pizza for around 25 hours per week and does nothing else. If I try to give him any advice or if I mention drugs he completely goes off on a rage that could last for hours, he threatens to kill himself, threatens me . I recently went into his apartment while no one was there and I found evidence of marjuana but it would have to be something more he is so thin. I do know that we probably need to cut off all funds but I'm so afraid he will kill himself. He is so unhappy and cries all the time. I know this is brief but what does it sound like? Drugs or mental illness?
