Ask HN: How do you deal with stress, panic attacks, and that evil voice?

Lately I've been having this little voice in my head that says "your doomed, your not going to make it, stop it" then comes stress and the panic attack with that "feeling" that everything is going to collapse.<p>The only cure I've been doing is to try and keep busy. It helps but that "feeling" never disappears. Edit: I'm bootstrapping entrepreneurship.
