Mate there are many ways to fight ,some styles like Ju jitsu are a combination of things that work probably better than boxing in a street situation or for protecting loved ones etc.
Different horses for different courses.
My bet is that if tested you'd be a demon protecting the ones you love.
Just dont call it into being bro!
Give thanks for what you got intead of concentrating on any negatives and it will continue.
In life we attract what we fear or we get what we concentrate on fully in order to out weigh our fears.
Boxing will be fun for you, just turning up to do it is the hardest thing for anyone to do ;especially continually!
Being there is fun then you get tested and if its still fun then it becomes addictive.
