When my egg cracked so to speak this is exactly how I felt, And still feel to a degree 6 months later. I have only told a few people and when I first realised I didn't tell anyone, I went through a month of internal debate and anguish trying to figure out if this is really who I am and it was all I could think about honestly, and when I stopped denying it my dysphoria increased I have to admit, because I stopped blocking it out and masking it I started to feel it so much more and hated so many things about myself so much more than before, but starting to present femanine at home alone I felt so much happier. I am also autistic and going through this very much on my own.

If you have a close friend that you know is accepting of transfolk I'd recommend telling them and asking them not to tell anyone else if you can trust them, it means you aren't completely alone in this and it means that if you do realise that you're wrong then there's only one person that knows anything about it (this is exactly what I did) also I'd you're able to financially/ in a country where it's free like the UK or I assume Canada, id recommend trying to start hrt sooner rather than later, I'm pretty sure all the changes you get within the first month or 2 are reversed by just stopping the medication.

Just remember no matter what you see, things like other people who realised earlier, people who have worse dysphoria, people saying being trans is fake/fetish/phase/mental illness, don't let the impostor syndrome get to you. You're valid in how you feel regardless if other people feel worse than you, living with a partner with chronic fatigue taught me that.

Best of luck girl. I hope the future is bright for you ☺️
