Bad taste in mouth, smell in nose. Freaking me out

[hypomom]

It's been a while. I'm back. I started having this horrible taste in my mouth and smell after eating that lasts hours. It is very bothersome and I'm thinking brain tumor as I know odd smells can be a symptom. i've also noticed I am "seeing" things. I'll think I see something move out of the corner of my eye and look and there is nothing there. Am i going crazy or is something wrong with me???

Anxiety is a natural reaction that occurs in all animals and is very useful in survival. It's purpose, similar to adrenaline is to raise all awareness and senses, causing a very alert and active state. The three things you described sound like a textbook anxiety issue.
