Oh boy, the same situation with me. I am a 23-year-old male too. In the college, I talk to a few "friends", and when I try to connect and express myself the people (in some sense) move away. For that, I developed social anxiety, depression and other problems (chronic tension headaches). I started in antidepressives but I couldn't sleep with it, so I take 2 antidepressives (one for anxiety and one for sleep). Recently I started to hit the gym doing aerobic exercises to help my mind. Almost the days I feel lonely, but it seems that I cannot do anything about it and sometimes I blame myself (Am I a bad or coward person?) and the guilty also explode in my mind... Sorry, I cannot provide any help tip...
