Absolutely with you there 100%, rdgrad15. Some of my earliest memories are of feeling a great gulf between me and the people who I came to realise were my family. And that gulf, over the years - due to the very kinds of things you mention - became wider and wider, unfortunately.
No, I think the way you're handling your family situation shows great introspect and self-care, tbh.
Also, I'm sorry it's been tough on you over the years, so I want to send you a hug. I appreciated reading your post.
