How do you know if you have anxiety or it's just spidey sense ?

For me it's anxiety if I experience one or more of the following:

Abnormaly dry mouth
Blurred vision
Increased heart-rate
Feeling like my insides are freezing over
Losing the ability to speak
Feeling like there's a massive lump in my stomach
Inability to concentrate/focus

Spider-senses: uneasy feeling in my gut. Not pain or discomfort, just uneasy.
