Clutch problems

Alright so started like a month ago, but it was realll hard to shift into gear. It would barely shift, it just would not want to go into the gear and id have to push the clutch in soooo far, all the way to the end. So I tried turning the fire wall adjuster to the right making it tighter. I went and tried the clutch, and it got worse, it wouldn't shift into first no matter how hard I tried and it would grind all the other gears. So I turned it the other way loosening it up. It worked perfect, my clutch was like a dream, I only had to push it like half way down and it would go into the gear so easily. Then about a week later it got back to how it was before. Extremely hard to put in gear and grinding gears. So now I loosened it up a little more, and its loosened all the way till it wont turn anymore. But it still barely goes into gear, to get it into any gear I have to extend my leg all the way and even then have to push farther for it to go into gear, I have to put the clutch all the way to the wall and push as hard as I can. And even then itll will grind real bad sometimes, and its realll hard to put into gear right when I get past neutral to go into the next gear its like it stops and I have to push so hard to pop it into the next gear. What the hell is going on, I can barely drive my car like this.

A few months ago I was driving my car and my clutch cable just randomly snapped, not sure if this is something similar or has something to do with my clutch cable. I have a King Cobra clutch I put in about 3 years ago, and a Maximum Motorsports FWA and quadrant. Help
