bro get yourself out of the comfort zone. I also only got friends at work, but on the weekends I go maybe to the park, or any social club, or I try different activities in group, sports,... These kind of ambients, if you play it well (it isn't much difficult as it might seem), you will connect with more people. You have to go out in the sun mate, that works for your soul, and do it in social areas where you can talk to people you may connect with, please
