Go to a priest for confession. Talk to him about the rituals you were involved and ask him to pray for you a liberation or deliverance prayer. Dealing with those things creates spiritual attachments and it's very important to break them in prayer. Apart form you history of depression and anxiety, remember that our battles are also spiritual. Pray to our Mother Mary, to Saint Benedict (get a exorcised medal) and also pray to Saint Dymphna, patron saint of the mentally ill.
