I know exactly what you're going through actually. I had a job as a civil tech right out of college not long ago. I lasted about a month before I gave up in defeat. With the amount of hours I had to work, the fact that I picked the wrong profession, and along with my serious case of social anxiety, I just couldn't do it. I just feel like I want to climb under a rock for the rest of my life like yourself, and not have to deal with anybody. So If you want a friend who's been where you are (still is for the matter), I'd love to have you as one. And I really hope things start to turnaround for you.
