Commend you for learning self defense and having a ccw permit. DO NOT take this as a discouragement, but tkd is not the best form of self defense. Most techniques taught today are for competition points. I have taken tkd for years, have also been in dozens of fights in my younger days. Tkd is a pretty art form, looks great in movies, but is usually ineffective in real world situations.
Look for an actual self defense class where no rule techniques are taught! (They don’t teach throat punches in tkd

)
As for your CCW, like mentioned above, practice and get used to it! It will always be your best form of defense!
Muscle memory!!
