Transgender Support Group
This community is here to support and help the large population of transgender people. If you or anyone you know identify as transgender, this is the place to share your feelings and experiences and speak with others who are going through similar things in their lives.
I am the wife to a MTF spouse. There is a specific group on this site for spouses of transgender. I don't know how to link to it but maybe you can search?
I have to say, what you are feeling is normal. It's a lousy situation that you have been put in and you need your own support aside from her. It's a unique set of emotions that this brings about and only those that have been there can relate. I urge you to join us on that forum as you may find it a bit more relatable.
Update: I found it.
