This day i've had a huge crying attack

It all started this morning, or well, last night, I couldn't sleep at all.

And today all I did was pace around my room and starting crying for no reason, i don't know why?

This days I've only mostly felt anxious about uni and other economics issues of mine, but i've never, even in the past, started crying out of the blue.

I don't know what's wrong with me i just want to feel better...
