I hate not knowing if it’s OCD or not. Any tips?

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!

Does anyone have any advice for how to know the difference between ocd and real feelings/thoughts? Sometimes an intrusive thought will come in and I immediately know it’s ridiculous and I can just leave it alone and it won’t bother me but other times I really really don’t know. It’s when ocd hijacks and twists my real feelings and thoughts and tries to manipulate me into believing they’re something they’re not or something that doesn’t align with my true morals or intentions. But since it’s twisting and mixing with real feelings I get so confused and scared. Everything gets jumbled and I feel like I can’t trust myself or my own mind. Yet other times and other topics I can laugh off and push away just fine. Make it make sense. And then I start to think well maybe I don’t have ocd at all and I’m just in denial because I don’t want to accept that these scary/concerning things are true about myself. Or maybe that’s just the ocd talking.
