That psychologist is a transphobe, I wouldn't go back if you can help it. If you can't find someone who is themselves queer, it might be worth trying to find one who practices "trauma informed care" and or treats CPTSD. Trauma informed care focuses on making the client/patient feel safe enough to work on problems; and bigots tend to be less likely to accept trauma from long term abuse/neglect as a legitimate thing, and often reject CPTSD offhandedly.
If you are in the US, there is a directory on Psychology Today that can be helpful, and telehealth may be worth looking into to expand your options. If you do go telehealth, watch out for chains like Better Help who got caught selling medical info.
I've learned in my personal search for a therapist that the first couple of appointments is/should be a sort of interview process where both parties assess if it is a good match. A specific provider could be the best one in the world while being a poor, or even harmful match for you. It they ard a poor match, you can always find another one. At this point I have a list of issues, like chronic suicidality and queer stuff, that I bring up while watching their response so I can guage if we'll get along. Sadly liberals and some leftists tend to be more likely to hide their transphobia/biases, so phrasing, tone, and body language are things worth keeping an eye on until trust is built.
Finding good (for you) mental health providers can be a lot of work, but is worth it.
