I know what you mean, Nerys. Being bullied has made me more sensitive as well, and also I guess, more aware. For the longest time, I used to be a very shy unsociable person because of this, but have slowly worked my way out of my shell. And like you, I've tended to question even friendly approaches from people because I feared it would be another prank. I did have a prank happen that way too once, going so far as someone calling the house and making disparaging comments or asking something unacceptable, which only made me more uncomfortable. That adds to a long line of reasons for getting frustrated easily.
