Help...?

Aw shite....
I really don't know what to do about all of this
My workload is piling up on me, I am 16 and in sixth-form. The teachers just seem to pile the work on.
I feel ill all the time, constantly have colds and i catch practically every bug that is going around. to top it all off i have an under-active thyroid, which basically makes me feel even worse. i have to take pills everyday for the rest of my life.
I also feel so alone at the moment. 11 months ago I broke up with my first love.
He doesnt even care about me at all.
I started to like another guy, I was thrilled coz it had been so long. Then one of my supposed friends went and threw herself on him. Knowing that i liked him. And now they are going out.
Great.
I am so weak.
I used to cut a fair bit.
But i stopped because I realised how stupid it was.
But i full on attacked my arm again tonight.
I really am weak.
I take all my emotions out on myself.
I dunno how the hell I am gonna hide my arm now.
Gloves to the rescue i guess -sighs-
I wish someone could help me, I really can't cope with everything at the moment.
So I have shoved it all into this, it isnt like anyone is really going to read this but if anyone does please dont leave scathing remarks.
This is here for me to write down my feelings, right?
So be nice.
Well i guess thats all for now, maybe i shall come and have another rant again soon.
Ciao
