Lack of motivation

My enthusiasm for archery has been quite low of late. My shoulder is still troublesome (I have an appointment this Thursday) but doesn't hurt enough to stop me shooting 30-60 arrows at a time. However, I'm finding it very hard to get the motivation to actually shoot. Fear of failure combined with the depressing effect of the setback of the injury are eating away at my mind, feeding my self doubt.

Gah.

Vent over. I'm sure I'll overcome it somehow. I'll do my exercises, shower and then sulk in bed with a new book.
