Yes, it is. It's a negative imperative. The imperative mood is used for commands, exhortation, requests, and other sentences where the addressee is being asked, ordered, or advised to do something.
In English, the imperative uses the bare infinitive form of the verb, i.e., the infinitive without a preceding to. Intransitive verbs in the imperative affirmative can be single-word sentences:
Freeze!
Run!
Testify!
When the imperative needs to be negated, it uses do:
Run, don't walk, to your local retailer before this deal expires!
It's also possible to use infinitive + not for a negative imperative, as in this triply-imperative quote popularized by Swami Vivekananda:
Arise! Awake! And stop not until the goal is reached.
Or as the angel Gabriel said to Mary,
Fear not!
(Gabe and Mary conversed in English, obviously )
But that form is archaic and/or poetic. Don't [verb] is what one would encounter in everyday usage:
Don't count your chickens before they are hatched.
Don't put all your eggs in one basket.
Don't stand so close to me.
Used intransitively, worry doesn't take a direct object. So yes, Don't worry is a full and complete sentence.
