I can relate. My worst bully was my Dad. Got bullied at school then came home to the real monster.
A lot of guys who are sensitive like you and me start in the gym for that reason.
Hey man, there's nothing wrong with being sensitive. It's a blessing and a curse because you feel the good things in life more, but also the bad.
I have learned to accept it. I'm even sensitive to compounds so I can take a 1/4 of the dose of say testosterone or tren and get the same effects. I also overreact.
That took courage to do what you did. Props brother! We are here to help
