Why is this script messing up with the animations, and possibly more?

--[ Variables ]--
local IdleAnimation = script.Idle
local Attack1Animation = script.Attack1
local Attack2Animation = script.Attack2
local randomattack = 0
local player = script:FindFirstAncestorWhichIsA"Player" or game:GetService"Players":GetPlayerFromCharacter(script.Parent.Parent)


--[ Animation Triggers ]--

function IdleAnimationTrigger()
    local humanoid = player.Character.Humanoid
    local IdleAnimationLoad = humanoid:LoadAnimation(IdleAnimation)
    IdleAnimationLoad:Play()
end

function IdleAnimationStoppingTrigger()
    local humanoid = player.Character.Humanoid
    local IdleAnimationLoad = humanoid:LoadAnimation(IdleAnimation)
    IdleAnimationLoad:Stop()
end

function Attack1AnimationTrigger()
    local humanoid = player.Character.Humanoid
    local Attack1AnimationLoad = humanoid:LoadAnimation(Attack1Animation)
    Attack1AnimationLoad:Play()
end

function Attack2AnimationTrigger()
    local humanoid = player.Character.Humanoid
    local Attack2AnimationLoad = humanoid:LoadAnimation(Attack2Animation)
    Attack2AnimationLoad:Play()
end

--[ Attack Scripts ]--
script.Parent.Parent.Equipped:Connect(function(mouse)
    while true do
        IdleAnimationTrigger()
        if mouse.Button1Down then
            IdleAnimationStoppingTrigger()
            local randomattack = math.random(1,2)
            if randomattack == 1 then
                Attack1AnimationTrigger()
            end
            if randomattack == 2 then
                Attack2AnimationTrigger()
            end
            script.Parent.Touched:Connect(function(hit)
                if hit:FindFirstChild("Humanoid") then
                    hit.Humanoid.Health:Damage(2.5)
                    hit.Humanoid.Sit = true
                end
                IdleAnimationTrigger()
            end)
        end
        if script.Parent.Parent.Unequipped then
            IdleAnimationStoppingTrigger()
            break
        end
    end
end)

This script is inside of a tool, inside of a union called Stunner. Multiple things are happening. Two things I know are going wrong are (I don't know why they are happening), The attack animation is repeating over and over and it's not stopping when I de-equip (along with the idle :/).

Can anyone bust this myth?
