I live in the big city. My job is managing many servers and clients everyday and I don't have so much time to meet people. I can't find anyone that have same my habit so I feel lonely and intimidating. And I want to become a normal human.
I go to many clubs to find the happiness from dancing, music, cocktail making, martial arts but I fail.
I try to check some online dating website and find someone like me but I fail.
I try to put myself outdoor and walk 20km but I fail.
Should I become someone or something else???
Learn to like yourself. Try not to be so hard on yourself. You might find that you are a great person with great potential. Friends will come, if there was a formula, I would tell you. Don't change because you think that yourself isn't good enough for others. I am sorry you are currently in this position and I know things will get better for you.
