How to stop touching my eye?!?

Okay whenever i feel like something is in my eye but really there isnt anything, i do this thing with my eye where I sort of rub the corner (the corner closest to the nose) and i put the tip of my index finger sortof inside it and put my tip of the thumb under the index finger and pick up whatever was in my eye, and i slowly drag it across my eye, (my finger isnt touching the eye, im just dragging like, a string of the wet stuff that is in our eye) idk what its called but im going to call it wet stuff, lol, and i always make sure my hands are clean before i do this, i wash them then i dont touch ANYTHING till i do that with my eye. i sort of just like drag the string of the wet stuff across my eye until it breaks from being stretched out. i do this all the time and always feel like dirt is in my eye and have to do it for hours and its embarrassing but i cant help it! PLEASE HELP! Im doing it right now as i type and its SO EXHAUSTING. HOW DO I STOP! PLEASE HELPPPPPP! :(
