I suggest you choose your greatest priority of the moment and commit to it.
It sounds like your priority at this time is the mission. If you still wish to follow through with that, if all your heart is in it, then nurture the little flame of your new self-discovery and new self-worth in privacy for a while as you finish up with your mission. Your priority may change with time, and being open may become more important. If it does, then respect that and let your circumstances change.
Best to you.
