Letter to psychologist

Here's the text that I send in an email:

"Hi Dr. ,

I was wondering if you had time to see a new patient. I have OCD issues involving self-confidence, perfectionism, motivation and communication which are slowing me down and decreasing my efficiency. I am seeing a psychiatrist for medication and a therapist for help with the emotional aspects of my issues, but I am looking for a specialist to help me overcome the habits and thought patterns that OCD pushes me into.

Thank you and I look forward to hearing from you."

Should I have used "Sincerely," instead? I don't usually. How obvious is it that I spend way too long writing emails?

Edit: my thoughts say I should have mentioned the bigger picture problem, maybe specifics like the fact that I look over the fundamentals. As if I wouldn't discuss that with them anyway.
