Therapy is definitely an important first step if you plan on transitioning, and i would do that before making any commitments either way, just to ensure that you are not making a mistake. Therapy will not answer all your questions but it will serve as a way of sorting out the issues that you have and revealing others.
As you mentioned in your intro you are experiencing the first instances of resistance to transition, and while it can get better there will undoubtedly be times when it will get worse. Just be sure of what you want and don't rush things, slow and steady is not so bad. One of the keys to all this is communication. Don't shut anyone out, and be honest and open.
Well i've rambled on long enough, again welcome

Chat later.
Steph
