I am also going through the same phase.

I used to be very good with the public speech and the confidence stuff with talking to almost everyone. In college my confidence started to break down for some odd reason- blame my parents for some reason. I had trouble breaking campus interview. I had trouble finding the job. It literally breaked my confidence in such way that I got close to agoraphobia. I work as a freelancer now from home. My family started treating me like failure ever since i failed to get job via campus. I sucked that and still keeping up with it. I know its hard to gain confidence and get back on competing with others. I decides to give my life another direction in the way I want to from my own strength.

I can't give much suggestion on interview breaking because I am also badly beaten on that side. I can however suggest that if you can get into freelancing, at-least you will develop portfolio which has nothing to do with your physical appearance, age, tattoo etc.
