hello jooker
i have had a simular exspiriance with my bother in law, we have really grown up together, but for him he was just sooo paranoid and for about a year he was trying yo kill him very weekend and was a reglar self harmer, he was always in troble with the police, it me 5 years to get him assessed and it reach a crisis before anyone would help, i know i live in uk so our systems are differant, after we finially got sectioned (under the mental health act 2) we finially got some aswers, which was great and started getting him some proffesional help and medication.
i just wanted to say i know what your going though and i it is very hard !!
he is much better now althou he is going though a lot again but coping brillantly i know if thing go wrong this time we are goin to have a big problem on our hands.
what i found we you cant really help them untill they want help becouse of there age (although your consent age migh be different in america)
i have now start my menal health nursing course in order to help other ppl like him
