Worship Getting Bad

I have been doing worship quite often for my cg that even some songs that I play my cg mates are like blurred and they laugh at me or think that I am doing some solo :( :"( I have to admit playing is not that good now too. Haven't been really practicing that much now. It's like the wanting to be good is like yoyo. At times I want to be good then I will practice many hours and when I don't bother, I just leave it as it is. I guess I still need to pick up my playing once again. Need to become better than what I can do now.
