How do I know the difference between health anxiety and health focused ocd?

This list by ai gives a good summary of my symptoms. Does it resemble OCD or is it something else? 1. Compulsions (OCD-specific behaviors): • Feeling the need to flex or contract muscles an even number of times, equally on both sides of your body. • Needing to reverse actions (for example, if you roll your eyes or trace a line with your finger, you feel compelled to do it again in the exact opposite way). 2. Intrusive Thoughts (OCD-specific ruminations): • Daydreaming about people you care about getting hurt (e.g., school shooting, injury, or kidnapping). • Sometimes feeling like you might want something bad to happen to someone you find attractive—possibly because of a desire to help or save them, though it’s confusing. • These thoughts can sometimes provide a twisted sense of relief while remaining distressing and confusing. 3. Sexual Orientation OCD: • Experiencing confusion or doubt about your sexual orientation. 4. Contamination Thoughts: • Feeling like things are contaminated, especially after touching something gross. 5. Sensory Compulsions: • Feeling the need to smell your hand after touching areas like your ear or hair. 6. ADHD-like Symptoms / Additional Observations: • Fidgeting or moving your legs when standing or sitting.

How to know if you actually have it or if I’m just making up the symptoms? I have a lot of intrusive thoughts constantly and even have a “theme” but it really surged after I search up what I was experiencing, but then again I search up a lot of what I experience and constantly have to recheck things. My parents say I’m normal but I know I’m not, (both of my siblings have adhd) I find it immensely hard to focus from turning 17-18. Please let me know what you think l! Thanks!

Hey, so I've never actually been diagnosed with OCD. I did a little bit of research, I always thought OCD was organizing things. But I'm not normal, I have this thing where I feel something isn't right. I obsess over it or if I brush my hand over something correctly then it's fixed. Or I have to do this thing on stairs, I'll walk up a few or down them because something isn't right. I read this thing on memories. I know something happened, but then I doubt myself to the point I don't know if it happened. And I think too logically in relationships. I'll put statistics on things and if they might not work out I distance myself, there's other odd things I do. My family always told me I was fine but then said things like I was messed up, and said to just ignore what I felt. Like I was making it up. I don't know what to do, I don't have a doctor currently, I was never diognosed. Is there a way to be sure I have it? Or a way to stop everything? I just want to stop everything, please and thank you. Sorry for the long post. If anyone can help, I would be so thankful.
