I think I'm losing it
That's concerning to hear. Why do you think you're losing it?
I think I'm losing it by doing this interview, I've never done anything like the masses before.
Interviews are really rough and scary, but you need to get your courage back up because you may not have the courage to improve if you're always scared. I suggest you talk with a psychiatric professional on what you can do to be courageous on your endeavors.
I won't do that. They put the crazies the loons in there too. If a real loony bin they should be proud of it.
I do not think that you're getting the point. You're not crazy if you think you're unable to have the courage to proceed to an interview, but you may need help in doing so. I hope you change your mindset and see it as a development or an improvement, rather than see it as you're crazy or you should be put into a "loony bin".
