How did y’all know you are trans?

I don’t know if I’m trans — I’m just questioning some stuff right now :3. I was talking to my therapist (side note: fuck depression), and she told me that the trans people she works with hate their bodies. For me, it’s not really like that. Sure, I’m uncomfortable going to the beach and showing my body, but I don’t hate it — I just don’t like it. But if I see a pretty girl, I feel this strong desire to be like her — to be pretty, have boobs, etc. If I’m not around people, though, I don’t really care. I don’t know… it’s just weird 😐. I also never look in the mirror and think I look good, it’s more like I look how I’m supposed to look ? but there’s not really like a connection? Maybe hearing your experiences I’ll get more of an idea what ist like.
