Anxiety sucks you have good and bad days and you never know which is which or when a good day can become a bad one. Today had a full on panic attack I was sure I was having a heart attack. Part of me thinks I have a heart problem. I was fine then I wasn't. How am I supposed to be sure it is anxiety. Gosh no one deserves to go through anxiety it is so underestimated as a mental thing that can be flicked away but it comes with these physical symptoms that don't go away.
