Why is my While statement not stopping when the test condition returns false?

Currently, I am having troubles with a while statement not ending properly when a condition isn't met. In whole, I am trying to make it so when the key "q" is pressed down, it sets "Held" to true then starting this loop and when it is pressed up, it turns "Held" to false and then stops this loop. I have confirmed through prints during these functions that it's working correctly.

while Held == true and wait() do
	local debounce = false
	if Held == false then
		break
	end
	local ray = Ray.new(char.Head.Position, char.Head.CFrame.lookVector * FireRange)
	local part, endPoint = workspace:FindPartOnRay(ray, char)
	local beam = Instance.new("Part")
	beam.FormFactor = "Custom"
	--beam.Transparency = .4
--	beam.Color = Color3.new(196, 40, 28)
	--beam.Material = "Neon"
	beam.Anchored = true
	beam.Locked = true
	beam.CanCollide = false
	local distance = (char.Head.CFrame.p - endPoint).magnitude
	beam.Size = Vector3.new(0.05, 0.05, distance)
	beam.CFrame = CFrame.new(char.Head.CFrame.p, endPoint) * CFrame.new(0, 0, -distance / 2)
	beam.Parent = workspace
	game:GetService("Debris"):AddItem(beam, (1/290))
	if part ~= nil then
		local human = part.Parent:FindFirstChild("Humanoid")
		if human and (not debounce) and (human.Parent ~= char) then
      			debounce = true;
    			char.Humanoid.Health = char.Humanoid.Health - .066
		end
	end			
end

Is this while statement not ending because the internals are somehow making it so it loops without checking the condition again? I have the whole loop inside a listener of the KeyDown event. If you are able to answer this, it would be appreciated if you left the issue and a solution.
