I've been super worried about my boyfriend lately because he's been very depressed lately and I can tell his mood changed and he gets super defensive talking negative and angry at me lately and I already know he isn't his normal self I'm worried his depression will probably get worst and he could possibly do something worst like trying to hurt himself I've been crying about it because I'm trying to help him open up and worried he could hurt himself I wanna  actually get some sort of therapy to cope with his depression how should I approach him about is abnormal behavior and him trying to get some professional help so far I only got a distress number that I can give to him but I wanna confront him first without him getting angry at me I know him for 2 years I can tell when he's not himself
