Dr. Leslie Dobson noticed a marked improvement in her patients during Covid when they were physically unable to spend time with people outside of their bubble. Then, as patients began socializing and working in person again, the same old anxiety, depression, and toxic stress reappeared. Dr. Dobson created "The Friend Cleanse" to help people decide who is giving you energy and who is sucking it away? Her deliberate decision-making rubric regarding how you spend your energy and with whom you spend it resulted in the book The Friend Cleanse.
