I feel like someone is chasing me. what can i do?

Get professional hlp: There can be any number of reasons you feel that way. Don't wait , talk to your physician or a mental health professional. You may have enough discomfort that sharing it with family or friends is difficult. A professional is not likely to dimiss it as nothing and will check it out with you. Family and friends may be tempted to make light of it, possibly delaying help.

Evaluate: Sounds scary. Ask your primary care doc to refer you to a psychiatrist so the underlying causes can be determined and addressed.
