You are still wasting your time.
As I said above, you are searching all lowercase, all uppercase, and all digits. This is 26 + 26 + 10 = 62 possibilities for each character. So for 8 characters, that is 628 possibilities. Divide that number by 8,000, and that gives you how many seconds it will take you to exhaust the search space. That works out at 865 years. (In reality it will be another 15 or so years more than that since you are searching for strings shorter than 8 characters as well.) This is also assuming that you did not use any symbols or spaces in your password either.
You will need to have some idea of what your password might be.
