Rejected Twice, Never Chosen, and Slowly Losing Sense of Who I Am

Recently I asked out my crush of 1 year, and she politely rejected me. I'm not here to rant or anything, as a matter of fact I've moved on from the rejection. The thing that bugs me is how I hold my life in contempt, like I've been rejected 2 times, accepted 0 times and forget about being confessed to. Not that all of it matters, but the people around me are successful in those things. I'm as of now so isolated and disoriented that I haven't gotten outside of my room for nearly a month. All of my friends tell me "Just wait for the right time, it'll find you too." yea bud sure, all of the reassurance come from those who already have those things. I'm socially dead, nearly every part of me is dead. There is barely anything or anyone for me to strive for. I've become so hollow that I'm often referring myself as a 3rd person because I can't recognize myself anymore. It's as if every part of me has slowly eroded without me even knowing.
