Is it weird to miss feeling anxious and a bit stressed out?

Anxious: Not weird, actually a pleasant feeling, especially if your anxiety & stress level are under control & you are doing great job maintaining that.

Not weird: Some people are "adrenalin junkies" and enjoy living on the edge. When life is too quiet they miss the "buzz". Within reason, there's nothing weird, wrong, or unhealthy about this, although if it goes to extremes it may lead to dangerous behavior and/or stress-related complaints. In general, there's no value in worrying whether feelings are "weird" — they just are what they are.

Anxious: Not at all. Several of my patients tell me that when they are in remission or stable.

Being anxious: Can become normative for a person. Many people use anxiety to drive them. The absence of anxiety may feel odd ; requires that you make changes to how you respond to life's challenges.
