In my opinion, yes, psychedelics can really be healing. This can be by micro-dosing or through heroic doses, depending on the individual. There is nothing like seeing reality break down around you to give you a more sobering perspective on life.
Shrooms will strengthen your feelings. If you feel like shit, imagine becoming a toilet in your trip. If you feel happy, imagine becoming lucid minded and enlightened. You can try a miniature dose of shrooms to feel insight of positivity come back to you. Not a normal or even light dose. I speak of a tiny little piece. See how you feel afterwards and integrate it into your life. Maybe after a week you will be ready for a small dose.
Use all consideration within this decision. Using psychedelics when you are not happy will likely always result in a bad trip.
