I am not a patient person and waiting on God is making me short tempered with everyone around me. Is that normal, and how do I grow out of it?

“Now Sarai Abram's wife bare him no children: and she had an handmaid, an Egyptian, whose name was Hagar. And Sarai said unto Abram, Behold now, the LORD hath restrained me from bearing: I pray thee, go in unto my maid; it may be that I may obtain children by her. And Abram hearkened to the voice of Sarai.”

Sarai had been promised a child and had waited a decade with nothing to show for it. Her solution was reasonable by the customs of her day, and it made life worse for everyone involved, Hagar most of all. Scripture does not lecture her about impatience so much as show what the shortcut cost. She is not written off, but the consequences run for generations.

“But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law.”

Paul lists longsuffering among the fruit of the Spirit, and the metaphor is doing real work: fruit grows slowly, and never by force of will. He was writing to a church tempted to achieve everything through effort and rule keeping. If patience is grown rather than manufactured, then your irritability is not proof you have failed. It is the ground where the growing is currently happening.
