Is Body Dysmorphia Disorder related to OCD or are they completely different disorders?

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.

Why do some people develop OCD?

I think we have to separate our OCD from our personality in order to treat it properly, yet at the same time some people say it's neurodivergent. And thats more accepting view, like when people say autism is just a different way of looking at things. But OCD makes you miserable so how can it be part of neurodivergent?
