when nothing works?

What do you do when nothing works and life feels perpetually pointless? I've tried therapy - it gets me functional but still unhappy, no answers, no meaning still. I'm too functional for my own good.
I feel like I'm just floating and existing. How do you keep doing this when nothing gives you any sense of meaning. Hobbies are just distractions, friends are nice to have, but nothing is enough to live for, ultimately.
Has anyone felt like this and found a way out?

No absolutely not, but I think being grateful for the things you do have will help. You have friends, and can afford hobbies..you are ahead of the game. Some of us don't have that, and to have some good friends would be a blessing. Not to moralize at all, but it's true.

There has only been one time where nothing seemed to work...where therapy and meds and self-help weren't doing a thing. I stopped eating, was hospitalized. The only thing that brought me out was ECT. Just an idea if you have tried several medications and nothing has helped. However, I see you didn't mention medications so is that something you would consider trying? There is no shame in taking meds if you truly need them.

I see this is your first post on PC, welcome! I hope you find your time here to be of benefit.

Thank you for the welcome Not really sure what I was hoping to accomplish here but it's nice to have a supportive response.

Tried meds before, didn't really do much at the time. Have a bunch left over I've been tempted to try again but don't have a doctor atm so probably not the best idea I guess. I'm nowhere near bad enough for ECT or anything. I pass as 'fine' and I am, functionally speaking.
Yes I should probably be grateful for that, having friends/money, being able to get out of the bed/house, but we all have things we should be grateful for - "someone always has it worse". Plenty of things I want that other people seem to have and can still be miserable, so I find that kind of thinking pointless. It doesn't seem to work that way.

I just want any sense of purpose or meaning back in my life. It's like one day someone flicked a switch and I couldn't 'unsee' how meaningless everything is. I feel empty. should I just give up on this changing? ...that seems to be logical after all this time
