Don't quit trying MiP. I've been around a while and at points in my life have had pretty bad problems with anxiety...I may know a little of how you feel. Couple anxiety with looking for employment and for sure that can be a pretty esteem robbing situation.

Don't quit trying. Even the most self-controlled and confident people have their moments...especially when they put themselves in the job market. The folks doing the hiring know this. The right people at the right time will see past that and see you for your potential. Just don't give up trying.

You do know one thing. You're a good person. Others aren't ignorant of that. The right people will see it and that's what counts.
