It sounds to me like you're having a lot of anxiety and maybe need to step back and take a deep breath. Remember that only you can decide how you identify and how you present yourself. Even if you should someday decide that you are trans, there is no right was to deal with it. Your would still be yourself, still have your relationship and your daughter. You wouldn't be obligated to change anything or even to tell anyone. It's something that's deeply personal.

For right now, be aware that your hormones, body and brain chemistry are in turmoil right now. Try to relax and realize that what you're feeling right now may not be anything like how you will feel when everything has settled down and gotten back to normal. Problems like OCD can be magnified or you might even temporarily develop other issues. Give yourself the chance to get through all that before you even try to figure out any gender identities.

If you should happen to still have these feelings when you get back to normal then, what I did when I started having serious thoughts like that was to do some in depth research. Not just about being trans, but about many different types of gender issues. Slowly I began to be able to pick out the things that resonated with me and the things that didn't apply to me at all. For me there was a lot of peace in finding the words that described me and being able to distinguish them from other identities.
