Hey, sometimes i have very unwanted thoughts enter my head and they scare me. I keep thinking that I am going to go "crazy", like I am losing my mind. I will have like "flashes" of hurting somone and then feel horrible for thinking that. Sometimes I will have a thought that I need to kill myself to stop these thoughts. Both of these things I will never do, but why do I feel like this? Sometimes in my mind I will make a small mistake seem bigger and feel so much guilt over it that it makes me super sad. I would never hurt myself or anyone else, but why do i have these thoughts? they scare me so much that i panic. Please Help
