Hi and thanks in advance. is excessive sleep, sleep attacks, grinding teeth, and itchy face and scalp caused by my ocd, depression and anxiety?

Most likely: All the symptoms you are referring to are anxiety related, certainly the teeth grinding , unspecified dermatitis.. the sleep excess or sleep attacks would require further evaluation though questioning and history taking for them to be properly diagnosed. I recommend you to do a formal psychiatric consult.

Anxiety & Depression: are mood disorders, as is OCD. Please see a mental health professional. If medication is used, please also get psychotherapy from someone who specializes in mood disorders. Learning to manage such conditions will be very helpful. See www.relaxationresponse.org for a self-help procedure also. Peace and good health.
