A Muslim's Cry for Hope

Salaams, everyone. I'm really struggling. Lately, I feel weighed down by so many of my own mistakes. A part of me thinks I've sinned so much that I can't possibly be forgiven, that I've realized my faults too late and my life has no meaning left. This thought just makes me feel more guilty and ungrateful to Allah for His blessings, and honestly... I'm just so tired. Sometimes, the idea of just giving up feels easier than facing it all.
