Leo Depression

I have a very good Leo friend (one of my oldest friends) I feel is falling into depression. Hows the best way to help with that and bring him out of it? I have a sense of humor he finds funny, but I'm afraid that is not enough. I've tried encouragement and validation.... what else can I do?

can i ask you wounded, is it possible for passing depression to turn into clinical depression? also, i have known people who have displayed all the symptoms of clinical depression but have got better without meds...so, is it possible to have like a passing clinical depression?

i just wonder cos i sometimes feel when i'm depressed about something, that it's an internal fight to stop me getting sucked into it and so perhaps if someone were to take me out, make me laugh or do the stuff the OP suggested, it would stop me from spiralling too far downwards...and might work for this leo too?

having said that, i'm scorp lol.

I believe its situational.
