You're not weak
I know this topic has been discussed before, but with many new people coming here everyday I think it's good to bring up again. I think we beat ourselves up when trying to quit because we think we lack willpower or are too weak, but once you understand the science behind how alcohol affects the brain it makes it easier to understand why it's so hard (but necessary) to quit. It helped me to put into perspective why I felt the way I did in the first 4-6 weeks after quitting, when at the time I thought I was losing my mind.
