Anyone tried ketamine?

I'm not usually a "better living through chemistry" kind of person, but I'm seriously considering ketamine.

I have CPTSD, anxiety, and, for the past year or so, a weird kind of angry depression where I'm unhappy all the time and lash out at people around me as if it were their fault. I've also been diagnosed with AudHD.

For a big chunk of my life, I've been externally successful anyway--I own my own business, am in a long-term relationship, and have all the trappings of nice house, nice car, nice vacations. But DAMN, my mind is a bag of cats and I'm seriously miserable most of the time.

I think that my immediate problem is that I've blown out my prefrontal cortex with reels and flash games, and get no pleasure anymore from normal things, and that I have the focus of a gnat.

I'm in therapy but feel like I need a brain reset to climb out of this hopeless pit. Anyone tried Ketamine? Especially anyone with anxiety, because of course the main thing holding me back is the fear that it'll make me lose all control.
