There are, sometimes, bad periods in your life.
Maybe a tragedy, maybe a lot of bad luck in school/work/your family, or maybe you deal with feelings you shouldn't have, and are something you're not suppose to be.

But don't give up, I beg you!
Don't give yourself in, 'cause I know you can do it! There is always light. Try to make a new beginning, 'cause tomorrow hasn't been made. Of course you can't just make it all disappear, but you can stop holding onto it, seeing this as your only hope. Everything will be good and become good with time...
and after all, time is irrelevant.
