You could start with a psychologist and they could recommend a psychiatrist for you to see. Alternately, start with a psychiatrist, and have them recommend a psychologist. However, from what you describe, I'd wager you'll probably want a combination of medication and talk or behavioral therapy of some sort.

I've found that the search tool on psychologytoday.com is very helpful. It's how I found my therapist, and she's been amazing. If you have insurance, you could also check your insurance doctor's listings to find someone near you.

If you're looking for a therapist, you would want to look for someone that specializes in anxiety and OCD. Also, consider what you would feel more comfortable with - a more skills based, therapist directed approach (CBT, DBT) or a more talk focused, client directed approach (psychodynamic therapy, etc)

If you decide to start with a psychiatrist, you may need a referral from your regular doctor, depending on your insurance plan.
