No, probably not, but it's hard/impossible to say without scientific data on tulpas - which does not exist as of now.
I am mentally ill (bipolar I), and I also have some friends who are mentally ill (schizophrenia, bipolar, etc), and we decided to try tulpa-creation together. Personally, I wasn't very good at it or committed to the process. I didn't see any change, and I don't think I ever created a tulpa. However, my friend's tulpa became a massive liability. Turned into psychosis very rapidly
Thank you, insighftul
Yes. Agree. Let's try to overcome conformity biases
