Hey TRP. For as long as I remember, I've been a coward. Back in school I was always afraid to speak up my opinion, or answer a question when teacher asked. Whenever I am dealing with situation which could escalate, like recently some drunk guy was talking shit to me and two of my friends, my mind goes blank I prefer to leave asap.

Basically, im shy and my frame crumbles as soon as someone threatens me. However, I noticed that I can keep my frame solid if the person threatening is physically weaker than me. How can I deal with it? Should I just lift weights until im the biggest animal alive?
