Sometimes I feel tension in my head or pain on my back and assume it's a tumor or some sort of serious illness. I made the mistake of google-ing my symptoms and came up with many terrifying results. Many sites say that anxiety symptoms can be the same as heart disease or other serious illnesses. When I start to think about it I panic and fall into an anxiety attack and assume I'm going to find out I have cancer and eventually die. I am only 23, I have so much life to live..
