Why do we have these thoughts what causes them when it comes to harming ?

I’m having a very bad evening with my intrusive thoughts. I was doing really good dealing with them but tonight one hit me hard. I’ve been having a lot of different intrusive thoughts but I’ll have one occasionally about hurting my mom or my dog who I love and they’re the only family I have in my life. They’re my world. I was helping my mom put away the dishes and I had the big kitchen knife in my hand and my intrusive thought was you could stab your mom. And then my brain said I had a twitch in my hand and that meant I wanted to do it. Let me just say that I wouldn’t hurt a fly. I actually caught a fly in a glass and put it outside instead of killing it this evening before this intrusive thought happened. I’m such a gentle and compassionate and caring person and these thoughts instantly cause me to have a panic attack. And I have no one to talk to them about. I know they’re hard for my mom to hear and I don’t want to be any more of a burden than I already am. I do desperately want to tell her and have her reassure me that I’m not crazy or a psycho. Then my thoughts wander to if your hand did flinch could you be a psychopath. Is hurting someone in you. I know it’s not but I feel like my mind is out to get me and hurt me. I’m working so hard and I thought I was doing so good but I need to know why I have these thoughts. They’re not ok. I need someone to help me make sense of why. I know we aren’t supposed to ruminate but I shouldn’t have thoughts like this about people I love and care about the most in the world.

Hey guys, I am having the worst HARM OCD episode I have had in a while. I am having disgusting, awful intrusive thoughts about harming others. It feels so real. It feels as if I am about to get up and just do it. The worst bit about it all Is I know I feel distressed and panicked. But where the thoughts are actually happening ( in my head) doesnt feel this feeling. This is making it feel worse as it really does feel like Im just going to do it. I am crying my eyes out because I know im petrified and dont want to hurt anyone im so scared. I have this terrible intrusive feeling in my that feels like its justifying the thoughts. Please can someone talk as I am scared Im crying I dont want know what to do I want this feeling gone I am so scared. I tell myself Id kill myself before hurting anyone else, but would i ? What if I actually do want to kill Please respond Im so scared

There are times my harm ocd has me convinced that my feelings of self harm or suicide and harm are real and that any moment I could commit the act on myself or my family. Is there anyone who can chime in on this. I feel like all the time I want to leave run away or avoid my family because of these thoughts. Like I shouldn’t be around my children and I don’t trust myself.
