By not give a crap do you mean not caring to transition, or transitioning isn't a big deal?
I was very easy going about my transition. I never corrected people when they used the wrong name or pronouns, never argued over anything, most of the time people aren't going to get it and it's pointless.
For me, pre-transition, my life was fine. I was well-liked, had relationships, went to college, etc. etc. just the more and more I learned about transgendered people the more obvious it was that I was trans. I don't want to say I "suffered". It was more that realising I was trans was harder and harder to ignore to the point where I had to do something about it. The only thing I really suffered from was dysphoria of my chest because I was almost DD it bothered me everyday to try to bind.
Would I rather have died than transition? No, but I would never have been this happy if I didn't.
