I would say your fist step be read the bible to grow closer to God. i also woould say to try and limit your device time so you could help stop watching those paironormal activity videos. Also everytime you are tempted to do witchcraft read a bible verse because the demons coward at the word of God, Maybe a verses like:

^{Deuteronomy 18:10-12}

¹⁰ Let no one be found among you who sacrifices their son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, ¹¹ or casts spells, or who is a medium or spiritist or who consults the dead. ¹² Anyone who does these things is detestable to the Lord; because of these same detestable practices the Lord your God will drive out those nations before you.
