exagerration re: maths

okay, so now it's actually bugging me because it is now not because i can't be bothered doing it, oh no, it's gotten much bigger than that i cannot do it, as hard as i do try. and to someone like me, who is usually capable of such like things this is extremely frustrating! and putting it off is an option no longer as the end nears and when i do fun things with my lovely friends i don't fully enjoy myself as it is always nagging me and the back of my head yeah call me a nerd, whatever. i want to do well x
