I think I'm experiencing psychosis from a video game

I've been watching people play dead space 2 and it's really been messing with me mentally and emotionally. I feel intense distress and like I'm in danger. There is a cult in the game called the Church of unitology and they have a phrase that goes "On purpose. One soul. One mind." It's very creepy to me but I'm afraid that I'm going to believe it and start chanting it. I've even been having intrusive thoughts about getting their cult symbol tattoo on my arm. I'm afraid that me and my family are going to get pulled into a alien hive mind cult and become controlled by the devil. My thoughts are racing right now and I can't stop crying. Please help me. 30M.
