One more post and then I promise, I will stop stalking
You once wrote to me..." I'd make peace with the loss before I shot so that I no longer had the fear, I would say to myself "hey, on the way to the world championship you're going to miss a lot of key shots, and this might be one of them. But if you overcome the fear of those setbacks and focus on giving your best to each opportunity you'll someday get there"
Maybe you are not doomed, to being alone or to accepting a world of 5 to 10 year relationships. Maybe this is just a time for you to accept and make peace with loss. I think you will one day have what you truly want.
