Has he tried mirtazapine?
I would say tread lightly and assist his needs the best way you can. It will probably be a slow process back to normality but give him space as well as let him know you are only an arms length away
He will need hope that he won't have to live depressed for the rest of his life.
Yes there is hope for that when he finds the right antidepressant that works for him. He may need to try several before finding the one that works for him.
In the meantime, he needs whatever helps him hang on and get by. You can ask him what would help.
A psychiatrist once said in a talk he gave that he had success telling his patients how devastating a suicide can be on the family. Sometimes the patient feels (wrongly) that everyone would be happier without them.
Best wishes.
He needs hope. That he won't have to live depressed like he is now for the rest of his life. Yes there is hope if he can hang in there, in the long run
Just be kind. Give him a hug and kiss. If he doesn't respond right way, just him his space if that is the case. If you can be there for him, let him know you care or ever love him. Things will get better. He will need familiar faces around during this time. Being isolated only makes things worse. Kind Regards.
That's tough, so sorry for both of you. I guess a lot depends on who he is when he gets out of the hospital -- someone who is on medication that has stabilized him, someone who realizes this was not what he really wanted to do, or someone who isn't any different than when he went in. Only time is going to tell you who this person is going to be, because once you've been hospitalized, life has moved to a different level. If he doesn't have the motivation to help himself, there's not much you can do, but you can make it not worse by just being you the way you were before, but you will have to decide if you're staying with him destroys two lives instead of one, and that just depends on how you both respond to his depression. Different people respond differently and have different levels of ability to cope when bad things happen in life.
