My old therapist from Ohio was nothing but helpful. From the very beginning, she told me that she would do nothing to stop me if I insisted on continuing transition, and would write me any letter that I wanted even if she believed that it was against my best interest, and thus encouraged me to be as honest and open with her as possible since I didn't have any need to worry about being gatekept.
And I was. And in a way, she's been through all of the ups and downs right with me, and has been a big encouragement in regards to continuing to pursue my dreams, as well as giving me helpful advice, and giving me both self-esteem boosts when I needed self-esteem boosts, as well as honest opinions when I asked about the prospects of doing the big steps like going full-time.
I just hope I can find a therapist as good as her once I go searching here in New Jersey.
