Don't know what to do anymore.

To start with i was going out with a guy i fell in love with and he dumped me for various reasons..... schools been going awfully at the mo so stressed and failed the january exams so extra work in the summer... my best friends close friend died last week so i'm trying to be there for her and doing everything i can and i also feel so sad about her friend passing away because i've met her a few times and she was so lovely and it's made me realise that i should really apreciate what i have more because life is only temporary.... this guy i kind of like asked me out and i said yes but i don't think i'm over the other boy so i feel totally confused.
sigh.
sorry for the rant and thanks for reading this... just feel so down...
