I have had a similar expierence with this, my mother would mostly ignore my input if I didn’t or did want to do something or if I knew she was wrong she would still ignore me and then find out she was wrong and rarely acknowledge I was right.
I never thought about this affecting me until I was watching an interview with a psychologist about 2 years ago and I really resonated with part of it but it never left my mind. Recently I rewatched it and part a different part of it resonated deeper when the guy talked about disagreeing with his parents even though they thought they were right and they listened… I was unsure of what exactly that part was resonating with so I listened to it again. I decided to mix up drink shake mixture but I couldn’t bring myself to do it for some reason I was just locked up about making the drink for like 10 min even though I know I wanted to make the drink. While trying to get myself to do it.
I noticed that there were internal voices that sounded different one was saying
do I want to go thought the effort to clean the shaker though
The other one though was saying
do you even want the drink
AND THEN IT HIT ME LIKE A TRUCK–THE 2ND WAS MY MOTHERS VOICE
Then I was hit with and started processing all the anger, sadness, and anxiety that I felt and didn’t realize I had pent up because of her ignoring me and brushing me off.
Its a tough thing to process and work through, I still am, but I feel better as a person now and more in control of my actions after the realization.
If I had to recommend anything to help, I would say let yourself feel those feelings you were repressing let them out in safe manners like writing down how you feel about stuff or hell I just let myself cry for like an hour after the dam burst it made me feel a lot better. Of course a therapist could help you too but the above two can help otherwise.
Also HealthyGamerGG is a really good YouTube channel with a lot of resources about mental health, it’s where the interview I was watching happened.
