No problem. I also went trough something similar like you, used to be a animu nerd (well, still am, but not as terrible as it used to be), really socially inapt, escapist etc., but I changed trough finding friends, going out and actually facing the world, which made me realise how much I wasted my life.
Think of it this way, you may have lost a girl, but you drastically improved yourself and gained experience, something that will last you for life. Just keep on going this right track and don't fall back in your old life, which I believe didn't honestly make you happy, no?
