I'm scared

Yeah, you heard me! I'm afraid to start running again. Every time I'm gearing up to go I start to feel like it's still sore, or too tight, or just plain old afraid I'm going to do something to aggrevate it! How do I get past this?! I know that I have to get out there and start again soon or I'm going to get too far behind. I am being silly...or am I? Augh!
