If it makes you feel any better - I still get severe bouts of imposter syndrome to this day. I don't think it'll ever fully go away.
Look at those feelings as indicators that you're on the right track, instead of something wrong! Change has been and always will be uncomfortable.
I wish you all the best on your journey! And you're always welcome to share more about it here. I'd love to hear about any progress you make/made ❤️
