Can I ask you OP, have all of your mental health problems completely disappeared since you transitioned? I know you've said you're happier, but has transitioning solved all of the issues you were previously experiencing?
Also, can I ask, are you autistic or otherwise neurodivergent?
I think the very aggressive stance that some TRAs have taken has made women need to defend ourselves and our rights quite robustly. In reality, most women don't really care about trans-identified individuals - lots of us are very happy and willing to accept anyone living their life in a way that makes them happy. What we're not happy about is TW being nominated for "woman of the year" type awards, taking the sole allocated spot for women in male-dominated environments, and most importantly, TW in female-only spaces such as bathrooms, hospitals, prisons, etc. Trans-identifying individuals have been given far more care and concern than women have ever had, and the erosion of our language, our rights, and our spaces - all of which have been very hard-fought - are what we're so upset about.
The vast, vast majority of us wish trans-identifying individuals the very best. We would support you in fighting for third spaces and would be opposed to any discrimination, but in return we need to see our sex-based rights respected too - which they very rarely are. I'm not referring to you specifically OP as you seem open to third spaces and identifying as a trans woman rather than just "woman".
Women that insist trans-identifying males should be allowed into women's single sex spaces typically speak from a point of privilege, Emma Watson being the perfect example. Women who have been sexually assaulted, raped, or otherwise violated and abused by a man often have a different viewpoint - a viewpoint which is supposed to be protected by the law allowing single-sex spaces.
