You arent cycled or have lost your cycle.

How long has the tank been set up? How many fish do you have and what kinds?

Do you know how to cycle a tank?

Your ammonia and nitrite are at toxic levels, high pH makes ammonia particularly toxic. You need to get the ammonia + nitrite combined no higher than 0.5ppm. Based on your readings that would take a 75% water change or 2 x 50% water changes.
