The list below is far from exhaustive, but it may be a good place to start. If you think you may have OCD or another mental illness then do some thorough research.
Lots of people who struggle with OCD or mental illness would benefit from seeing a therapist. Talk to your doctor, search online or ask people you trust to help you find a professional to talk to.
