Your personal profile tells us nothing, ergo, I shall infer that you are not a pilot.
A go-around is a perfectly normal manoeuvre, which professional pilots are trained to perform, with the minimum of fuss. It might seem somewhat dramatic to the travelling public, but that is because it is carried out using full power, below max landing weight, so the performance (angle and rate of climb) is impressive. The thrust-to weight ratio on a go-around is considerably higher than that for a normal take off.
I stress, it is no big deal for a professional crew, however, it is a busy time in the cockpit, so it might be a few minutes before the Captain can give that reassuring PA to the passengers.
Windshear has caused me to go-around from the flare. Those two big, beautiful Rolls-Royce Trents on my A330 just punched in, and our wheels did not even kiss the runway. It was effortless and we were throttling back at 2,000 feet in no time at all.
I hope that this reassures you - drama it is not.
