Samantha,
A diagnosis of schizotypal personality disorder is generally not very difficult to make and it would be unusual to confuse it with Obsessive Compulsive Disorder, although it could be confused with schizophrenia. One common feature of schizotypal personalty disorder and OCD is that both patients may exhibit superstitious behavior.
Zoloft, an antidepressant, can be helpful for depression and OCD. I recommend that you express your concerns further to your psychiatrist and ask for clarification. It is very important to work with your physician to improve your condition.
Please keep in mind that this information is intended for general educational purposes only and specific health concerns should be directed to your personal physician.
Sincerely,
HFHS MD-JM
