Is my fear of being a psychopath just symptoms of OCD? I'm terrified.

I’m so scared I don’t even know if this is OCD at this point. I keep having horrible intrusive thoughts on acting upon my worst fear and the feelings and thoughts are so strong and intense I’m genuinely convinced I might lose control and do something horrible. It feels to real and it’s so constant that I don’t trust myself at all. There are times where it even feels relieving to think about doing something horrible even though it’s the opposite of what I want so feeling like that is so confusing and it’s convincing me I’ve become my worst fear. I’ve been trying everything to avoid anything that brings these thoughts and feelings up because I’m just so scared I’m going to snap and do something horrible. I have therapy soon and I’m really glad about that but I’m scared to tell this to my therapist because I don’t know what’s going to happen. I just need to know I’m not the only one who experiences this because I feel like I’ve just gone crazy at this point. I’m so scared that this isn’t OCD.

It started a month ago on vacation. I started getting intrusive thoughts about harming my loved ones in their sleep and it scared me so bad. I thought it would stop but it only got worse. Here I am a month later and things have changed drastically. My thoughts have now shifted to becoming some serial killer. I am so worried it’s all I think about. I can’t stop thinking about the things I did as a kid and how it could validate all my thoughts. I don’t wanna hurt anyone or anything at all. I am so scared of the thought of the notorious serial killers that I’ve heard about in the past and I can’t stop comparing myself to these horrible people. I’m scared because I used to be mean to animals as a kid and people say this is the first thing to look for in serial killers. I remember still having a lot of empathy for them when I was young too. I look back and cant at all understand why I was like that. It makes me wanna breakdown and punch myself. All of that stopped a really long time ago and every since I have done nothing but helped and empathized with animals. I am every surrounded by them and consider them to be more family than pets. I get extremely upset over anything or anyone who is suffering. I just can’t get that memory of me doing that stuff out of my head and I’m afraid it means it validates my thoughts I’ve been having even though this is not what i want to happen. I’ve been completely avoidant of alcohol and refused to take a medication I was prescribed because irritability was a side effect and I’m afraid of snapping and hurting someone. I just can’t stop thinking about my past and how it could correlate to now. Even though I have grown up to have morals and respect for everything I have a fear that it’s all been a lie. I get so much anxiety from thinking about this stuff. I haven’t eaten in almost 3 days because my stomach is in a constant knot and when I do eat I feel too guilty to do so because I’m not paying attention to these thoughts and sometimes it makes me question whether I secretly want to do bad stuff which I don’t and that scared me so bad. I made an emergency appointment right after I started having these thoughts and they diagnosed me as having schizotypal personality disorder. They said I have been having ocd “tendencies “ because I have the thoughts and constantly googling everything which I guess would be a compulsion. I have been looking on forums for people with past actions similar to mine to see other peoples reactions. I’m not sure what this is anymore. Idk if this is ocd or I’m just using it as an excuse. All I know is that I’m extremely scared. I vowed if this stuff as everything something I would even think about doing I would take myself out before I ever hurt anyone else. It’s scary but it’s what I always tell myself when I doubt any of this.

Idk if I have ocd or not I just want to know about 4 months ago I started getting harmful thoughts to loved ones im very scared because I would never hurt anyone. These thoughts scare me so much because they are so vivid and I have like these urges as if I’m going to do it. What is this? Am I ok? Am I going crazy please someone help it feels like I can’t take it anymore living this way with these thoughts haunting me day and night.
