I have abbys phobia, and scared of the void

So basically let me get straight to the point, i have phobia of the abbys and i play in this smp so basically I wanted to make a trap for a person to get their heart and that trap is going to be happening with the void but i am that scared that i can't even go to the end dimension because of the void phobia, so how can i make that trap.I tried using texture packs to change it's colour but couldn't find one , so if anyone's know how to deal with it please tell me otherwise i couldn't even join the end war which is happening soon
