How Did You All Learn To Accept Yourself?

tw: some transfem specific experimentation (marked with asterisks **), some mentions of dysphoria (or lack thereof)

Hey, everyone. I've (18, mtf(?)) been having a really in-depth analysis of what I want and who I am for a couple days and I've really been digging into the lingering questions around my gender identity.

In fact, I've had a lingering suspicion that I am trans for almost a year, and of course it's ebbed and flowed in how present this discussion was in my life. When I was busy with stuff, I could think about it less, but it was never gone, and I couldn't escape it when I had time for myself.

I want to say I'm trans or cis without doubting myself, and it's gotten to the point where thinking about it makes me feel physically ill to a mild degree.

(tw starts here) A couple days ago, I used a hack that I found to make a DIY bra. I put it on and it made my heart flutter and I felt ill to my stomach, which can happen sometimes when I get excited.

I think that somewhere deep within myself, I know the answer, but there's something so obviously stopping me from being able to accept myself. I guess I'll go over some of the reasons that I doubt myself:

1.) I don't really think I have dysphoria. I think that if I made the active choice to continue living the gender I was right now, I'd have some doubts, but I'd be able to do it, if that makes sense. I think the closest things to dysphoria are my adamant refusal to go shirtless in public, which could be body insecurity in general and hatred of body hair, which... I don't really know how to explain.

2.) I had no signs as a child. I know that it's not necessary to be trans, but I feel like it delegitamizes myself.

3.) Like I said earlier, I can go long periods of time without worrying about my gender.

Like I said earlier, I think I now the option deep down in my heart considering I've spent so much time wanting to be a woman, if even a little bit, but I guess I'm just waiting for some sign to confirm that I'm trans. So, anyways, fun rants aside, how did you learn to accept yourself, and how would you recommend someone else learn to accept themself? Thank you for reading.
