Where's the Work?

I have been actively looking for employment for almost 2 years now. I get a few interviews, and then I'm avoided like the plague. I'm wondering why I haven't been hired yet. I have all the qualifications these people are looking for. Yet for some odd reason, I haven't been offered a job at all from anyone. WHY???!!!???!!!??? What the hell is wrong with me that nobody wants me? This doesn't fair well with a person who suffers from severe depression. Yes, I take medicine for it. No, I don't show it at all when on an interview. Then what the hell is the problem?!? This doesn't help my mentality any at all........
