I don't think the harm data means you need to go pay a yogi $400 for lessons.
I think we need to stop telling people meditation is a perfect little peaceful practice and instead treat it like ibuprofen.
If you are meditating and you start feeling anxious or in a bad way.. stop. Stop meditating and go do something else. Maybe talk with a therapist.
If you start feeling depersonalization.. stop meditating.
You should inform your medical practicioners that you meditate, the same way you tell them if you take ibuprofen on the regular. They probably don't care, but it's good to know.
You probably should ask yourself "is the benefit from meditation exceeding the side effects?" If no.. then stop doing it.
Taking more ibuprofen is not always the right course. The goal of meditating should not be to meditate more.
