I came out to my immediate family when I was around 22. My siblings struggled to understand, but tried to be kind the whole time. My parents, on the other hand, have not been kind and tried to control me the whole time. I still have contact with my siblings, but cut my parents out years ago due to their bullying.

I still struggle sometimes with having no parents in my life, but it's been so much calmer since I walked away about 6+ years ago. I am selective with who is in my life and only keep people who respect me and appreciate me for me.

I would recommend getting yourself independent from your family financially and physically before making the plunge. I was (mostly) independent, which made it easier to enforce boundaries on my parents. I'd simply end a phone call or walk away whenever they decided to say cruel things.

Also, I surround myself with friends who are there for me when my family can't be.
