Yes - but it's a question of degree. Think of it as having a comfort zone, a challenge zone and a breakdown zone (where it's all too much or you've been in the challenge zone too long).
Entering the challenge zone brings discomfort. It's a warning from your sub-conscious, protecting you. You need to listen to it, analyse it (via your conscious mind, obviously) and decide where to step into the challenge zone or step back.
Usually the key is to step in (little steps!) again and again. That way you get used to it.
This is why you had these feelings; they're perfectly normal.

With trad, little and often is generally the best way in. Good luck!
