Strains vary based on genetics and growing conditions. I would reccomend trying a high CBD indica or indica-dominant hybrid. Start with a small dose, perhaps a few drops of tincture, or one small inhale from a vaporizer, or a little piece of an edible. Take a walk outside in a safe place, take slow deep breaths and notice the world around you. Stay in the present and notice your thoughts, but dont worry about them, just let them come and go and continually re-focus on your breathing. Expand your belly as you inhale and gently contract your abdomen and pelvic muscles as you exhale.
