Emotional despair

I just lost someone who don't even care for me. But he just lost someone who really care for him. I realize that I wasn't good enough, I am not what he was looking for. I've been crying myself out for the past few days, trying to convince myself that this is just a phase. But somehow it strikes me that this is not a phase, this is not a stage of a happy relationship. This is a breakup, this relationship is not going anywhere, it's over. I slept the whole day, praying to God "DON'T WAKE ME UP" because I'm afraid. I'm not ready to deal with tomorrow, I'm not ready for the future and I'm not ready for waking up and deal with the fact that I'm alone. But this is life. This is how it works. Nothing last forever but you can always hope for a better future. x
