What to do if i have irrational fear, should i talk to a shrink?

Yes, or psychologist: Irrational fears are often best treated by cognitive behavioral therapy. Medication is usually not involved (but might be rarely). This has been a specialty for a long time and it is often handled successfully. Ask foe a referral or look up cbt psychologists in your area. Ask questions and try until you find one you trust. Good thinking!

CBT for some works: In contrast to other forms of psychotherapy, cognitive therapy is usually more focused on the present, more time-limited, and more problem-solving oriented. In addition, patients learn specific skills that they can use for the rest of their lives. These skills involve identifying distorted thinking, modifying beliefs, relating to others in different ways, and changing behaviors.
