I think I let my depression finally win

I think it's okey, I wasn't meant to be in first place. I'm really tried, everything, really everything I do only backfired. I feel horrible, I don't see any solution anymore. It's simply enough. Therapy? No progress. I'm still stuck in life. I'm still 0. What should I do now? Just acccept it and finally let go? I'm clueless, each day I feel like I'm drifting further and further away, just being left alone. So many days have passed and I still suffer. If not any by any chance a miracle happen soon, I'm just giving up.
