Do you ever feel unworthy?

I know I do. I always have tons of things to do yet I fight sleeping! What the heck? I have nothing to be upset about yet I am consitantly trying to sleep my life away. Or it feels that way. I have so many things I am supposed to be doing and starting up. I'll take another nap. I feel so unworthy most days. I wish and pray that God will help me through this!
