The comment about puberty being an exciting time, and thinking that being scared rather excited was evidence of dysphoria, struck me as well. Are any young girls excited by the prospect of periods? I certainly wasn’t, I was scared and resentful and I wanted it all to go away. I didn’t even start my periods until I was 13- relatively late these days- and I wasn’t ready to hear “you’re a woman now”- that idea terrified me. It’s a massive, irreversible change, and that combined with the hormonal fluctuations means that fear is a perfectly natural reaction, not a sign that something is wrong.
