some things i dont know why

I realize that i seem to keep most of an arms length away from people. im not sure exactly why. i think part is because i am afraid of myself. that i will unintentionally hurt those that i do let in too close. i have an immense fire that burns within me and im afraid if people got too close i will burn them just because it's the nature of the fire within me... either that or the only other way for people to get close enough to me is to  dwindle my fire down to a pile of embers though it would not have been their intention.
