Why this happens to me when im happy..

The starting of december.. im reali down lost my soul, lost my strength. Im reali lost right now. This is what u call love, love sacrifice for one another, care for one another, trust one another.. When u reali love that girl, u wud do anything and in the end nw, i just suffer like that why? i cant sleep, whenever i eat i vomit. Did i do anything wrong? Why her friends just dun allow us? Im not a bad guy, i dun do harm.. Why my friends dun trust her too? at least im happy that my best friend reno still ask me dun give up on her, so thats why i wont give up yet, there still a chance, i believe in this, God pls be with me, I still love her very much, just her no one else.... can i dance still? can i still go on? i dun dare face my family like this, i dun dare face my friends too, im so tired now i din sleep for 1 whole nite but even do im damn tired i cant sleep sigh.. it takes time for me to recover rite now. I will try to change myself from now on, i dunwan be the same now.. A different kind. I wont be a happy go lucky person already, inside of my hear full of anger and ready for all kinds of obstacles ahead.. Peace
