Cutting and self harm

Does anyone else have the strong urge to do some sort of drugs sometimes when there ocd gets really bad or over nothing in general, like I’ll just be sitting doing nothing and my brain goes “you need to do cocaine right now or else” and I get a urge and it’s so like odd to me??? I’ve never done drugs in my life and never plan to because my father was a addict and I’ve seen what they’ve done to people so it scares me when I get these thoughts and then I get the urge to reach out to someone who can give me drugs and I play this whole scenario in my mind where I contact someone and I meet up with them and pay them for the drugs and then I take them and die and it’s like??? Idk I’ve had weird intrusive thoughts involving drugs before but this is like different if that makes sense, I also can’t stop focusing on how my body feels when this happens like it’ll feel like I was a previous addict and that I’m going through withdrawal and need something or else and it’s just so weird to me. Anyone else go through this?

I can't do this anymore I feel fucking insane my mind keeps telling me I want to k word people and if feels like my mind is making fucking plans. I'm diagnosed with ocd but I don't even know if it's ocd what if I'm just a terrible fucking person that actually wants to do this. My mind is literally telling me to go buy a weapon and hurt people like I get fucking urges. I can't keep food down and have not for the last few days I feel like I need to go to a mental hospital but I don't want to burden anyone in my family. Like my mind tells me specifically I want to do this but I don't want to but recently ive been having the thought of what if I did do it but I don't want to. I just want it to stop I'm a good person I don't want to hurt anyone at all. But what if one day I actually do want to do something. I can't do this anymore.

I am so so upset and anxious right now. At this point I badly need reassurance as Im feeling a whole panic attack coming on. Has anyone ever had the feeling in their head and body like they are actually going to act on a terrible harm related intrusive thought like it actually feels like you are. Im scared as fuck i dont know what to do because What if i actually do that i am so scared does it ever feel like your on the edge of doing it and you get this whole intrusive urge in your body PLEASE REPLY please tell me experiences
