hi, i need some advice on mental illness. i am worried about my partner. Male 27 years old. used to smoke marijuana both the real and synthetics and drank alcohol a lot. He is now experiencing some mental health symptoms, but does not want to go and see a dr. Symptoms include mood swings. for example he can be totally normal, for hours or even days..... then he can seem really down he can get angry easily and then he can be overly happy at times, then be completely normal again. he is also hearing voices, which he can literally believe everything they are saying. (so finds it hard to trust me) he says they convince him. he has had depression in the past. but this seems to be way more than that. we have 4 kids...... i need advice. what is this mental illness?
