I can't and wont tell you to stop the statin, but I can tell you that "difficulty walking" is a common symptom from statin poisoning.
You asked "if I quite taking this drug will I have a heart attack?" Nobody can promise you that, but I would encourage you to research NNT scores on statins. (Number Needed to Treat) which addresses the question how many people have to take the drug to prevent a bad outcome. The answer is anywhere from 88 to 288 people have to take crestor for a period of 1.9 years to avoid a bad event ( heart attack or stroke)
You need to look at Lipitor, Zocor and Simvastatin on this web site. These are all statins like what you have been taking. You need to look at the official side effects for statins. Many of us have been on the same painful scary trauma you are suffering and it can be a long haul getting out of it. Lots of fish oil, 6 - 10000 mgs through out the day, along with quality COQ10 (ubiquinol not ubiquinone) and 3000 mgs at least of Vitman C spread through the day certainly helps the situation and gives the heart muscle a healthy boost. There was an advert in the Wall St Journal by the manufacturers of Vytroin that said "This medicine has NOT been shown to prevent heart attacks" unbelievable eh? Good luck to you from another poisoned victim in New zealand.
