There may have been conspiracies among pool chemical manufacturers, but CYA based chlorine is not the result of one of those, if they existed.

You can operate your pool with your existing CYA level, but you need to
#1 - find out what that level is, by doing the CYA test on pool water diluted 1:1 with distilled water from the grocery. Multiply the result by 2. If the adjusted number is near 200, dilute 3:1 and multiple the result by 4.
#2 - Order a K2006 or K2006C kit so you can test high chlorine levels.
#3 - Use the Best Guess page in my signature to determine what your chlorine levels should be.
#4 - Stop using stabilized forms of chlorine.
#5 - Drain your pool if that's the option you prefer, but ONLY IF you can do so safely. It's not an option, without professional help, on in ground liner pools, or on concrete pools in low wet areas.

Whether you can swim safely this weekend is hard to say, when you don't know what either your stabilizer level, or your chlorine level is. Keep in mind, too, that you don't want to make the news the way that Boston area public pool has, by having found a mom lost for 2 days 'hiding' in the bottom of THEIR cloudy pool.
