This month i started dealing with blinking ocd. i can't stop thinking about blinking? how can i treat this problem?

Habits like that are difficult to break. Try to concentrate, control your breathing, focus on something else. You could also consult a psychotherapist for help.

Please see a Psychiatrist. There is medication to help with this. Also seeing a Clinical Psychologist with expertise in multiple types of psychotherapy can help you cope with your issues.
