How do I get rid of the demon zozo

let me tell you something that happened last night\ this morning. my friends and I have done Ouija board sessions many times. one of the friends we'll call C, he wasn't much of a believer until what happened. my other friend we'll call D was leading this session this time. we called out to zozo, C and I where not scared at all and we just kept provoking zozo cause we where getting nothing from the board and yes this was a bad idea on our parts, im normally much more smarter then that but I could tell it wasn't me in away. we stopped the session as soon as D stated to kinda have a seizer and we snapped him out of it. we did automatic writing to see if we could get some more answers out of zozo. it just ended up with D basically having another seizer type thing. we pulled the pen and paper away and saw what D wrote "RUN RUN' was the first time we tired it but as we kept going we tried reading some shit for exorcisms and what D did was something ill never forget and it doesn't help I have videos as proof of what was happening. during one the trances I put him in when I simply pressed my palm on his forehead to see how hot he was getting, he lifted C off of him and I can tell you regularly that D could not do that. D started to go for the back of Cs shirt but I stopped it before anything could happen, a few seconds after that D was trying to lunge at me and try to kill me. we ended up tying up D so we could try to sleep but C had to be up for work at 5 and we finally could try to sleep around 4:40 but C and I couldn't sleep but D slept for a little and managed to untie the knot D put him in (a bondage knot).

I am now basically babysitting an adult and im literally a 17 year old. please don't do what we did, it doesn't only harm one person but it effects everyone.
