I had a lot of doubts to begin with. Part of what helped me was learning that it’s not useful to think of words like trans as prescriptive, but as descriptive. I started only thinking in terms of benefits and making myself comfortable.
I want to wear different clothes and otherwise present myself differently because I’ve always wanted to? Then I’ll do that.
I tried HRT and I liked the mental and physical effects? Then I’ll continue with HRT.
I have no connection to my name and prefer a female coded name? Then I’ll use a new female coded name.
Etc. etc.
Trans is just a word and the more important part is making yourself happy.
Edit: The word trans is useful because it describes a bunch of the stuff I’m doing, and it makes me happy when I see things that are trans supportive. I think it’s also worth remembering that gender is a spectrum and that being transgender is defined as not identifying with the gender you were assigned at birth/not being cis, and therefore includes a lot of identities and ways of expressing yourself.
No one else gets to go inside your head and tell you how you feel, so it’s only up to you to decide whether or not you are trans. Honestly you can do a bunch of gender non-conforming things and even do all sorts of transitiony things and stuff associated with being trans and then just decide to “not be trans” if you feel like it, even if others might describe you as such. What do they know anyways? Most people haven’t really put their gender identity under the looking glass or even so much as read about the subject.
sounds like you have a lot to learn yourself
