"My problem is what’s officially called a “process addiction,..." — Elizabeth Gilbert quote meaning

My problem is what’s officially called a “process addiction,” as opposed to “substance addiction,” which was Rayya’s downfall. Process addictions are characterized by extreme compulsivity around certain behaviors—gambling, shopping, hoarding, eating, sex, control, obsession, gaming, skin picking, etc. Put simply: Rayya was addicted to drugs; I am addicted to people. Although I do believe that Rayya was a love addict, as well. In fact, many folks in the rooms of recovery surmise that love addiction is at the bottom of all the other addictions. Our famished yearning for love is the great yawning chasm that we keep trying to fill with other things—with drugs, alcohol, food, money, sex, cigarettes, gambling, gaming, success, perfectionism, workaholism, internet addiction, you name it. Of all the human desires, the need to feel loved is the most fundamental. When unmet or perverted at a tender age, that need can warp our brains into making dangerous and even insane decisions for the rest of our lives.
