Help request with the meditations for depression, anxiety, PSTD

Dear community, I have studied Dr. Joe Dispenza works by youtube interviews mostly and highly interested in the meditations for curing depression, anxiety, PSTD, to reprogram genes. Does anyone have any suggestions, recommendations where I can find those type of meditations or materials in books about curing that? Thank you for any help 🙏

EDIT (26/05/2023): I also have a polyps on a gallbladder. Doctors say it genetic, so I need to work on it too. So as I understand for now I need to visualisate healthy gallbladder and feel state of wellbeing to trigger self-regulate signals to cure it. Am I right at this point?
