M small heart and this big world

In persian we have an expression thst says "my heart has grown thin recently". I think this is true about me. 

I can't call it getting hurt but there is this thing  inside my heart that gets sad and surprised by lots of things going on around me. Then I become alone and heal myself again till the next person comes around and tears that thin line in my heart again.  It feels like a woriness when this happens. 

Well!!! That's how it is I guess.
