If you're not there for yourself, man, then no one ever will, 'cause all they'll be able to see is someone trying to find another to live off of emotionally, which is a one-sided, parasitical behaviour that everyone avoids.
You are the only truly consistent element of your world. Everyone and everything else is temporary. You can either accept this and learn to move on, or there will be no one else on this planet who hates your life more than you will.
I wish I could help you, buddy, buy you a waffle and talk it out, but the best I can do is to remind you that all human beings are in a constant state of self-creation, and thus are capable to shape who we are and how we respond to external events. You have a choice. You can choose not to be defined by your one-sided attachments. You can choose not to inflict this loss upon yourself, which is fake since you never possessed, and will never possess, anything. Time owns everything, and like the pictures of a slideshow, all will pass, and something new will show up.
You have a choice. Remember that.
