what’s the point of living if i know my life will never get better?

for weeks I’ve been trying to find a reason to stay alive, but nothing feels convincing anymore. I’m not in an immediate danger, but I’ve been suffering every day and I can’t see a future where I’ll feel truly happy or satisfied with my life.It feels like I’m stuck in this endless cycle of pain. I don’t have hope that things will get better..tbh feel sure they won’t,but why should I keep going if life is just going to be like this forever? why do we stay alive when the future feels so bleak?
