I'm really hoping somebody can help me out with this!

Backstory:
I consider myself to be a 7-8 on the trans spectrum, where I want to transition, find myself looking it up regularly etc, but cannot because I would lose the relationship with my parents, my wife and possibly my child. I'm also 6ft5, wide shouldered, long armed and frankly look ridiculous from a number of angles. I've accepted that I will always be male, and I have made a good life as a man.

Now, for me, crossdressing occupies my mind in the same way that my eating disorder occupies it - I am restless, frustrated, and sometimes incapable of doing things until I "get my fix".

These feelings hold so many similarities to me, it has me wondering why it's accepted that transgender is a legitimate thing, and it's not a disorder like binge eating, or any other compulsive activity.

It's questions and failings to understand like this one that are holding me back from fully accepting myself. I think that if I can answer this question I would feel so much better about being transgender.
