Well that was a lot to get off your shoulders! Hopefully coming here and letting it out has provided some amount of relief. Know very well that you are not alone and you've found a great place for support.
First, if you haven't already, I would suggest looking for a therapist who may be able to begin helping you work through all of this, specifically one familiar with gender concerns.
Then, start looking into local resources and support groups (or look in the next town over if you're concerned with getting spotted). Not much better than making RL friends who can work through this with you and share experiences.
Beyond that, this site hosts a wealth of information and is frequented by a lot of really great people, so by all means, read and share at your leisure!
Any way about it I'm glad you found this place and hope you find it as valuable of a resource as I do!
