Guitar Playing Damm Bad

Man, I suck now at guitar playing. Played for worship the other day and I was like total screwed. Not only that some part of my lyrics were wrong and my mates we laughing. Darn it seems when I do worship too close to one another, nearly back to back or every 2 weeks my playing will be screwed up. I admit here that working OT is causing my guitar playing to be a little screwed. My timing is now out. Darn I guess I really need life balance to become good in the stuff that I do.
