Help please.Be honest please. I'm a struggling mom

Please read and comment kindly. Really looking for support. My child was laying across me and every time I breathed a certain way I was getting a groinal sensation. I kept breathing like that anyways (ugh idk why), and then my mind told me I had hurt them that I might as well do something else because what's more. So idk why or what overcame me other than the thought of doing it and causing another feeling (I literally had to question what to do during this and the only thing I could come up with was to move my elbow towards her groin area) but it came across my mind to elbow my child, and I elbowed their crotch or side area. Which caused another unwanted groinal sensation. Then I began FREAKING smooth out and asked my child to move. Then I've been stressing since. I feel like as a mom I don't deserve to be theirs anymore. Idk what overcame me, and in the moment, it felt like I wanted to move my elbow, but I know that can also be my OCD speaking. Right? I clearly regret it all and hate myself. I would never intentionally hurt my child; I don't know what happened in my head when this happened. I was doing SO well! Is this my POCD that I've been diagnosed with by my OCD specialized therapist? Just a struggling mom who used to be the best of the best. I'm very depressed by this. Idk what to do with myself. I live in regret now, and I just wish it would've never ever happened. I can't stop ruminating and being depressed thinking I don't deserve anything.

TW- POCD people only please. Am I a criminal hiding behind a diagnosis? I woke up in the middle of the night breathing and I was having groinals because she laying across me. My mind told me I had already hurt her so might as well do something else. I then was like well I have nothing to lose and I had to think of what to do. The only thing I could think to do was move my elbow towards her groin area to cause a feeling. Well I did that and my elbow touched her groin and caused an unwanted feeling. I then immediately asked my child to move. After that, I went back to sleep but I believe in a state of shock as to what happened. I woke up panicking completely thinking I have done ruined my life. I was going to prison and would lose my child. Since then, I haven't stopped ruminating. I have had days where I feel okay, but then there are days where I can't stop crying. Thinking I don't deserve my child, and I deserve to be in the ground. I was on a new medication that was causing me to spiral and giving me insomnia during this time. I wasn't getting much sleep at all. Since then, I've slept on the floor, and I eventually got my child to sleep in their own bed to avoid this happening again. I got off the medication and feel so much better with my thoughts and sleeping so much better. My daughter tells me how wonderful I am often, but I don't feel that I even deserve to celebrate Mother's Day this year. I'm not a good mom. I was four months ago before I spiraled. What's wrong with me? (edited)

Please help me. I need support. I just need someone to be up front with me. Tell me the truth. I want to get past it all. I'm struggling STRUGGLING today. My mind is telling me I'm the only one who is dealing with something like this. Idk why I did my biggest fear. I was put on a new medication when this happened which caused me to spiral, my thoughts to be more often, and have insomnia. I have been diagnosed with POCD as well. I woke up in the middle of the night when my child was laying completely cross my chest. I was breathing and having groinal sensations. My mind told me that I assaulted her by this, and I was going to prison for it. My thoughts started going like this, "you're already bad might as well do something else", "no sense in stopping now" "you can finally do what you've always wanted", "what would you do if you could do anything to cause harm" So I had to think of what to do in the moment. The only thing I could think to do was move my elbow towards my child's groin. In the moment it felt like I really wanted to do this. I proceeded to do so, and my elbow touched her groin. I immediately told my child to move off me. I then went back to sleep. When I woke up, I began panicking, confessing to a family member what happened, and crying immensely. I feel like I failed as a mother. I'm in such distress since I started sleeping on the floor to avoid it from happening again, and I got off the medication. I'm so much better OCD wise since I got off the meds. I was the BEST mom months ago before this happened. The thoughts have always bothered me, and I was always scared I would give in and act on them. I'm living my worst nightmare. I feel alone. Felt so wanted in the moment and SO real. Ugh. Could someone just give me some support? (edited)
