I know the feeling, but please don't. Go to all the clubs and student organizations that interest you. Talk to people during lectures. Form study groups, do things with people, have fun. You will feel like not a piece of shit, and you will be more motivated to do well in school. In the first year I was the most active and outgoing, and it was also the year I did the best academically. The year (second year) when I was shut in that didn't talk to people was also the year that I failed courses and felt miserable. By third year, I finally made some friends that I could connect with, but by that I time I had already fugged my schooling up. I would go to my friend's place and they would work on file systems, kernels, neural networks in group projects, and I would sit there awkwardly because I was repeating a course from the year before. I dropped out 4 years ago and now work at a shitty dead end job.

 

From one Bernd to another, I am giving you the advice I would give to my past self. Become involved; give yourself a reason to wake up every morning. Also, study groups are very important, please join one! They sound lame, but they are not! You will dutifully study and make friends in your field. It is the same principle as going with a gym partner. Much better than anhedonia and wanted to kys, anyway.
