I'm really losing it

Today's friendly, I did badly even though i did score but even the simplest fast break balls i couldnt catch it. I know i'm not suppose to let it bounce! Cause i should know that i'm not tall enough to catch it, if it bounce. I hate my clumsiness, Mr teo even said my stamina dropped, I can feel that too. Coke kills, But Maybe its not because of coke, its myself. I dont know. Gr, I have never been under such stress for basketball and studies, I think i'm gg nuts.  

I think i should really loosen up? 

Or is everything failing down on me, And i'm losing it.
