<s>[INST] I have a son whom I'm living with right now, and I can't beleive what im seeing and hereing from him.  His temper is unreal and you would think he was a 17 yr old boy ... this man is 43... he only hangs out with much younger guys.. I am so ashamed of him I don't know what to do.... He likes to live in his own trash with dishes in his room as you  would see in a teen .. wears clothes that i would throw away... what can i do [/INST] DearWe understand your concernsI went through your details. I suggest you not to worry much.  The given information may not be enough to understand your brothers character and diagnose his problem. But I do understand he is leading a life style which others cannot accept and for which he never cares, and if somebody tries to advise him, he do not like it. Borderline personality disorder symptoms are somewhat identical to his condition. But need more information for a proper diagnosis. He need counseling and psychotherapy. I shall provide you with the required counseling and psychotherapy techniques online, to overcome these problems. Please describe the whole problem in detail and post a direct question to me.Hope this answers your query. Available for further clarifications.Good luck. </s>
