My parents hammered me about it. "You'll never make any money. You need a job with benefits." They thoroughly discouraged me from following any interest that I had!
The control in my house was more subtle, but ohhh I can relate to this! When I turned 18, and it was time to make decisions about post-secondary education, I remember thinking to myself, "I'm 18, I'm an adult now, and adults make sensible decisions for the future". Which of course did not include anything creative, artistic, social sciences/humanities. Nobody said those words to me... .I think I just absorbed the message.
One plan I do have is to start some light Tai Chi work outs from youtube or something. Something heart friendly.
This makes me happy that you are finding a way to do martial arts even though you have some physical limitations

And... .you know that tai chi isn't just senior citizens in the park, right? I did a tai chi class a few years ago... .I was going to a student acupuncture clinic (reduced rates) at a traditional Chinese medicine school, and one of the students who treated me invited me to go with her. I don't know how much you know about the philosophy of tai chi, but the master would often show us the martial arts application of the moves we learned, and he explained to us that it is about yin and yang... .that if someone comes at you with a lot of force (yang), rather than meeting that with force of your own, you would yield to that force by becoming "empty" (yin)... .the best I can describe it is, receiving and redirecting.
I can't understand why my parents made everything in my life such an ordeal.
Based on what I read in
If You Had Controlling Parents by Dan Neuharth, I would guess that they have unresolved trauma of their own (or their parents did). Not all parents who are trauma survivors try to control themselves, life and other people, and not all controlling parents are trauma survivors, but there's a correlation.
