OCD doesn’t have to have rituals necessarily but that’s what most people think of as a hallmark of OCD. A differential dx like this is important, but hard to do without a professional who can help you not just list your symptoms, but assess the qualitative nature of them.

Regardless, it does sound like this impacts your functioning and happiness, I’m glad you’re reaching out and getting some support.

I agree that sensory sensitivities are also more common in ASD, but ADHD, especially in more severe cases, can also have sensory sensitivities as can OCD and other conditions.

OP I think there’s enough here to justify an evaluation by a psychologist if you can afford it / it’s available where you are. If not, reading about ADHD and applying some of those strategies will not hurt you. I’d recommend ADHD 2.0 as a starting point.

ADHD and anxiety are also comorbid, and some of your symptoms may be more about anxiety and might respond well to anxiety related interventions. ACT (acceptance and commitment therapy) has several good workbooks about anxiety which could be helpful.

You could consider getting a psychological assessment that will give you an idea of your cognitive strengths and weaknesses. They can also administer instruments like the Strong Interest Inventory if you’re still looking for help deciding on a career.
