My son is exhibiting symptoms of mental health disease such as risky behavior, extreme weight loss, behavior changes such as becoming more femininate. He is wearing women's clothes and now states he is andriodguness. He is having risky behavior such as jumping off a moving truck (foot is still swollen although improved) refuses to see a doctor, will pull homeless individuals off the street and into his home. States medical diseases are not real and don't exist. He weighs 125 lbs @5' 11". Use to take great pride in his appearance. No longer has good hygiene. Fluoride is in the water and they are trying to poison us. He is eating more natural so not to provision himself. He is on a fast ans supposedly will be for the next few weeks. He is only drinking certain types of water alkaline is one. The only nutritional source is soy milk. His high school friends were shocked by his appearance. If any comment is made to him about eating or concern about his health we are considered negative. He doesn't want negativity in his life. He has been out of the Marines for 4 years and a traumatic divorce for 3 years. He absolutely refuses to see a doctor. He is not suicidual or homocidal. I am a nurse but he doesn't trust me even when it comes to his health. States he only gets 3-4 hrs of sleep per night. We live in California so I don't know what else I can do.
