Yes I've had my little spells too kurt. The compulsive checking and re-checking is one of your means of coping with your current anxiety. Have you tried relaxation techniques. Perhaps learning about meditation, exercise, talking to those you trust, or even breathing exercises work well. Its good to handle issues but its good to look past those small problems that will go away on their own. When we compulsively take part in our little twitches its likely that we are just not dealing with certain feelings we have and you can stop it if you want to. One thing I do is, stop the behavior just for a second, take a deep breath and feel the pain, whether it be fear, anger, sadness, guilt etc. It hurts but you'll find soon after you wont tend to have that twitch and youll feel a lot better. Just be sure not to overwhelm yourself with those feeling.
