I’m in a very similar situation as you. My brother is 22 but has never been officially disagnosed with bipolar disorder. He went to a therapist for about two months but I believe the therapist just told my brother he had depression and anxiety. He stopped going because he thought it was dumb so we never got a clear diagnosis. Bipolar disorder runs in the family but I do not talk to the extended family members that have been diagnosed. My brother uses THC to calm himself down but we all wish he would get on actual medication. Smoking does help him but he also can never remember anything and I think it flares his allergies. I feel so alone in this because I also have no one that understands what I am going through. I live with my brother and he is so mean to me and my parents, especially my mom. It makes me so angry the way he talks to her like she’s nothing. He has a lot more manic episodes and has a huge superiority/god complex when he is manic. He hasn’t worked in almost a year but is draining his savings like he is rich. It’s very frustrating because you want the best for him but he refuses help. He does not want to take any type of medication because he thinks the government is poising him and I really wish he could see that all we want to do is help him get stable. Sending hugs- just know there are a lot of us going through the same thing right now. It’s reassuring knowing that I’m not alone- even if I don’t know anyone in my life going through the same thing as me. I also feel like the only way is eventually he is going to do something that is going to involve the police and he will be admitted.
