Going nowhere fast

Is it true that you're unable to love someone if you cannot love yourself? I've witnessed the battle between what I want and what I need, and resent myself for letting this war rage on for so long. I know this isn't good for me, but I am in it for the rush of our chemistry. Perhaps my heart has had enough of my foolish mistakes and therefore refuses to let me feel again in order to save myself from another injury. Regardless of why I am the way I am, I hate it and cannot construe a solution that could mend such a tedious affliction. I love you, but not myself, so where does that leave "us"?
