Question about mental illness, why do I always try to find somthing wrong with me? I'm constantly googleing symptoms then getting all worked up. I'm pregnant and seem to be getting worse. What can I do?

See therapist. It is impossible to answer such a question online. Everyone has individual issues.
Self Esteem. You sound like you are insecure with yourself. Talk to you ob. My line to my patients is usually "tell me everything that is going on and then sit back and enjoy your pregnancy while i worry for you and guide you along".
