Health Anxiety

How can I get over health anxiety? I feel like something is always wrong with me. Anytime I see anyone diagnosed with anything, all of a sudden I start feeling the symptoms, and get anxiety thinking I have it too. 😭 It’s so out of control. I’ve had what seems like acne scars on my upper and inner thighs for about 12 yrs and I’m scared to get it checked out thinking they’re going to diagnose me with something serious. I have back pain, and always fear the worse. I get breast pain, and think I have something serious. Ugh.
