Dysphoria is never constant for me. As for questioning whether you're trans or not, you can't be 100% sure, but then there are people who think they're doing OK, and then find someone and go on to marry them but their dysphoria gets more intense after marriage, and they either have to hide to save the relationship or risk it by coming out.

Maybe you found the right person and the right job, but you haven't figured other things out, like your personal life, and that's when you'll feel like trans again... who knows?

maybe a gender therapist will help you sort it out, but maybe you've tried that already, apologies in that case.
