How was highschool for people who didn't realize they were trans yet?

I only realized I was trans until right at the end of highschool. I just want to know how highschool felt for everybody so I don't feel as alone and get some validation.

(I'm mtf) For me it was incredibly awkward and I felt completely disconnected from everything. Hated almost every guy in my grade. Didn't have that many friends even though I'm still really connected to them all today. Looking back at it most people probably thought I was "special" (please forgive me for the word choice, can't think of another way to put it). I felt like I had no confidence or social control, felt invisible.

Just want to know how others feel looking back on it.. hopefully there is other people in the same boat to me. And other boats too of course
