I think the most significant part of your post is where you say you're not even sure if you're trans or not. When my wife (MtF TG) started therapy, I was gobsmacked to find out about all the other conditions that sometimes can cause transgender-like thinking without having ->-bleeped-<- as the actual cause! Going to a competent gender-therapist is definitely a good start. He or she will be able to help you safely explore your emotions and discover what is causing these thoughts.
As my own brand of reassurance to you, I'd like to remind you that gender is not necessarily an either/or option. I, myself, am bi-gendered, though genetically female. While I would LOVE for medical science to figure out a way to grow me some man bits to add on down below without having me give up what I've already got, I know that's not real likely in my lifetime. So, I help myself stay sane by giving my male side some air time. (For example, tomorrow there's a football game he wants to watch, so I'm making space for that and a beer. 🙂 ) I'm also a writer, and in the trilogy I'm penning, I have a character who is FtM transgendered, but he elects to not do any physical transformation due to his successful career as an actress. In both my case and my character's, gender is a sort of grey muddle, but we both find ways to make ourselves happy where we are.
As with all other areas of life, there is no one path to take, just a whole bunch of options and trying things out to find the best path to happiness.
Best to you on your journey!
