I don't.

Lately I've realized that my life is like a roller coaster.
Up and Down.
Hot and Cold.
And the same way goes with my mood.
And I'm tired.I swear I am so tired.Surprising myself with my weird reactions and my behavior.
I don't like the same things i liked and i don't want the same things i wanted.
And most of the time I don't know what's wrong with me.
I think I am changing in some ways.
But don't know if it's good or bad.
Lately I don't understand myself a lot and I'm tired of trying.
