Shaky clunky car?

So, my car usually clunks over bumps and what not. No matter the speed, and it’s not only when turning. It’s a pretty bad clunk. But I was driving home at about 35 MPH, and it sounded almost like something may have broken, and the car got super shaky, and I had to stay under 30 MPH to get home. I just went and looked under the car and saw nothing hanging down or out of place. The alignment is bad, and I noticed my driver side tire is worn on just the sides almost bald. Middle of tire is fine.
