If your family doesn't respect you, that's not a good thing.
If you have lost respect from your family, how and why would you regain it?
My family came to the point to respect more my BIL than me.
Happened to me, I was conditioned to keep my mouth shut, never say what was in my mind, always telling me to change my personality to match what they wanted and always tell them good things I did for validation.
For 27 years I was the nice guy conditioned to do that, until I found the red pill.
First it was very hard, but when I started being successful financially and realized I didn't need any if my family, I placed my boundaries in place, mom crossed them, I kicked her out of my house when she was visiting me. Never spoke with her again for a out 3 months, after that the dynamic changed.
Put your boundaries and don't be afraid of enforcing them even with your family.
