Let go or hold on?

When will you know when you should let go or hold on?

When it is really painful already, maybe when I can finally see that there's no chance anymore that's the time I should let go. But right now, I'm still holding on to the fact that I still love you. I still want you, after all this time, after everything you're still the reason why I want to smile, why I want to love. You're still the reason behind every blushed face. I still love you a lot. I still love you. I'm sorry but I'm still in love with you. I know that everything will be alright. But please, I don't want to love you anymore but I can't fight it. Your memories are still inside my head. Please, please, please help me. I know everything will be alright but I'm dying inside. Please come back to me. 

I've been denying it to my self for a long time now. I don't want to accept the fact that it's still you. But it' such a relief letting go of this. I hope everything will be alright soon.
