I've just realized something as a 24 year old guy. I honestly believe one of the main reasons I'm so depressed is that despite my repeated efforts over the years starting from 15 all I've had is rejection after rejection whether it was genuine interest in someone or trying to have sex.    
**I SWEAR TO GOD** I tried my best: experimented different ways of approaching women, went to the gym, wore nicer clothes and shoes, took better care of my skin, groomed my hair and beard, fixed my teeth and whitened them, perfume... you get the point. I can safely say there's little potential for more growth in this department. I guess my personality is just too shit and I'm not made for this sort of thing.  
I know getting a girlfriend won't magically fix my issues, but I don't think most people understand how frustrating and hard it can get to suppress such a fundamental instinct we humans posses. I'm at a level of distress that I can't even properly masturbate anymore.  
And please don't suggest hiring a professional, if I had to do that it would be the final nail in the coffin for me. It would be like admitting that even when I tried my best, I wasn't enough for anyone without paying them. How fucking sad is that.
