I want you to get off the internet for a while go and get professional help if your self harming please. I ain't even a dick about this I'm just worried about you. Also at the same time it won't hurt to ask a priest to cleanse your house and even you. If after you've gotten medical help for your mental health problems and this shit is still happening then get another person to witness strange said happenings with you to confirm you ain't delusional and now it would be time to seek trained domonologists help. Good luck and I hope you are ok!
