What are The causes of harm ocd? Mine attackes my Child. Will IT ever end?

Hi there! I am 4 months postpartum and struggling with harm ocd, the fear of what if I harm my child. It has manifested to the fear of what if I harm my husband, sister, nieces, parents, etc. Anyone else have this experience and how did you get through it?

I had blood work done for a test I was having a couple weeks ago. The phlebotomist hit my vein weird, my arm bled a lot, but eventually stopped. My arm is still sore several days later. The following week I had my bronchoscopy. The nurse used the same arm that was already sore to put in the IV for the meds. My arm started hurting, swelling and burning. I told her it hurt really bad but she ignored me; then I was out. It’s been a week and my arm still hurts, and my veins are tight and hard. Couple that with the white stuff all over my face, that nobody from the care team bothered to wipe off- which I didn’t know about until my husband asked me what it was, I got harm from my OCD! At first I chalked it up to the white stuff on my face was bad bedside manners. Now, I keep thinking that my doctors and everyone associated with the clinics are trying to harm me. This morning I had an incident with the fryer oven while toasting my bagel. I asked my husband about it and he says he didn’t notice anything. I was down to the last few bites of my bagel, and suddenly started feeling loopy. I spit it out and threw the rest away. After sitting awhile thinking of the doctors and phlebotomist etc… it dawned on me that it was my OCD telling me people were trying to harm me. I don’t know how to get over the fact that my arm hurts really bad and my doctor completely ignores my health concerns. I’ve been nauseous for the past two weeks or so - there is definitely something wrong! I think when they find out that you have OCD and/or Anxiety, they treat you differently, as if you’re making up the symptoms. I most certainly haven’t felt heard! My husband always says, what’s wrong now? It’s such a horrible feeling to hear him say that. Is this what you call Harm? Or is it associated with Harm? I’m not sure if this is triggering or not. I hope not.

About 2 months ago, I sliced my arm so deep in an attempt to make this all go away.. as there was blood spurting like everywhere my life flashed before my eyes and I could hear my parents laughing in the room beside me. I started screaming for help as my eyes flooded with tears. How could their little girl do that to herself?? I was able to get to the ER and have my arm stitched up.. making my attempt a fail. But I’m so scared. I don’t want to do something like that again. I’ve never seen my parents cry except for then. The fear in their eyes haunts me up to this day. But that’s the only thing that relieves my pain. Can someone help or relate to this ???
