Please, if you did not pass the first time, DON’T GIVE UP! It took me twice on the FE to pass and 4 times on PE. I passed the PE just before I turned 50 and I am now retired. It was worth trying that fourth time and made a difference in the last chapters of my career.
Don’t give up.
Don’t get discouraged.
Pick yourself up and make a good plan based on solid advice (given above and other places in forum).
Stick to your study plan.
Work problems for most of your study time. It will force you to look back and learn what you don’t know without spending a lot of review time
