Am I a failure? Should I cut off my parents and buy my own place already?

I'm 26 and have a government job.

2022 vehicle

Pay my own expenses and cover my parent's truck note/bill too. I also give them money for any other expense that may occur.

I've never asked anyone for a favor.

Own 6 acres of land with farm animals in it.

However, I'm living with my parents because they depend on me financially and if I move out and cut them off financially they're going down. I've cut them off in the past because they were being ungrateful and after a few months they talked horribly about me to my older siblings.

I can't help but feel like a failure because I'm still with my parents. It's crazy because... if I cut them off they suffer and if I stay my older brother will tell me it's time to grow up and move out yet he doesn't help my parents and he's on government assistance... not sure why he'd even say anything. Wait... i know why he's in my Business, my parents talked horribly about me when I stopped giving them money for being ungrateful in the past. Anyways, i feel like a loser.
