So so so tired...

Sometimes, things can get really tiresome when you have to think and think and 2nd guess what others' are thinking.
My experience from past lessons taught me never to set expectations that are too high or even normal. It's tiring trying to meet expectations all the time. Why dont we just take a step back and be ourselves rather than try too hard? Makes life easier.. Communication is still key and it's the main problem still.
I'm like a loudhailer, facing a bottle of pent-up feelings.
What should i do? i'm already trying... I thought everything was fine and dandy, even great! but apparently that's just on the surface. The turmoil beneath the surface was something i wasn't expecting and it bothers me that i am clueless.
Why?
