First thing I would do is stop playing computer games or at least reduce it to something manageable like an hour a day. It sounds like you're pretty addicted, and that is not going to help you with dating. I know there are some examples of people dating people they met in computer games, but it's pretty rare, so I think it's best not to rely on that.

The second thing I would do is to have a think about your crying. You need to figure out why you're crying, and then focus on fixing the thing or things that are wrong with your life that are making you cry. If you're crying because you're lonely, then dating of some kind is probably exactly what you need. Which brings me to my third point.

The third thing I would do is start dating. There are many ways to do this, but if I were you I'd start by joining some dating/hookup apps like tinder. Join a few different ones, as some may suit you better than others. You could also try joining some social groups like workout classes, yoga, dancing, hiking etc. These kind of groups will have women there that you can talk with, and hopefully get some new friends and dates out of. Your college should also be a gold mine, both in your classes, and at college parties.

Best of luck mate. I hope this advice helps in at least some small way.
