Hah, I used to be the same. I promised myself if love didn't work out, I'd give myself peace but alas a few friends jumped in at a critical moment and I am still clinging onto life.
You see, love is important to me. It used to drive me more than anything else in the past, finding it is what I lived for and once I found the right person I was forever bonded to them in a way, I chose them and would never choose anyone else. Maybe that is the reason why life has felt utterly pointless ever since I lost that and came to terms with the fact that I am emotionally unable to ever love the way I used to or trust anyone else out of fear. I was naive to think things would work out so long as I held onto what I believed in. Nowdays love is merely a lie to me.
