Do you have anxiety? I do, it makes me feel uneasy, and worry a lot, usually just a generalized feeling
I have ADHD which causes axeity if I do not take my medicine, because I literally can't do anything right or finish anything. So yes at times. 
ADHD is not fun either, I have that too, a lot of people see it as a mental disorder, but I do not
For me, because I cannot function without medication I feel it is, but I think for those who can manage it without chemical intervention it may not be
Yeah there are certainly levels to it, anxiety sometimes is appropriate, but the difference is how regularly you suffer from it
Yeah, the thing about that is that it can be all by itself or it can be a result of an untreated disorder, like ADHD, OCD, skitzophrenia etc. 
That is scary to think it is almost like a ssign of other issues!
Yeah like a symptom. I was treated for anxiety and bipolar at first because thats what they thought I had, but then once they figured out it was just ADHD and the other two were eliminated with treatment of ADHD. Its hard thing to navigate! Few things are as intricate as the human brain!
That is for sure! Bipolar disorder is not fun at all, longs tretches of depressions, elevated moods and all
Yes! I agree. Post partum depression is really scary too.
