My boss is selling to a DSO and I'm freaking out

Found out yesterday that the owner is selling the practice to a DSO. He's been my mentor for 8 years and I genuinely love working here. The DSO wants to keep me on, but I've heard horror stories about DSO culture. More patients, less time, corporate BS. Do I: 1. Stay and see how it goes? 2. Start looking immediately? 3. Try to buy the practice myself (probably can't afford it)? I'm panicking. This practice has been my home.
