In the age of at-will employment, it very well may have been completely out of your control, so don't beat yourself up.

If it was due to your performance, then you know what you need to fix for next time, so don't beat yourself up in this case either.

Enjoy the weekend, don't worry about your resume. Catch your breath. As /u/etchasketch4u pointed out, these events can often be a case of something better coming down the pipe.

You're 100% right that drinking would only make the situation worse. There will be other jobs, many places are desperate for people right now so this is one of the best job markets in which one could have a job change. IWNDWYT :)
