Honestly, I can relate to your situation - been there, done that. I think I am a step further now, I kind of found a fitting lifestyle for myself. The absolutely first thing that you really need to do, is finding a girlfriend.

Don't worry about being nerdy - there is someone out there waiting for you! You are an attractive man. Finding a spouse will dramatically improve your quality of life.

There are enough options to reach this goal. Online dating comes to mind, but it might take a while to find the right match, so hang in there!
