Default Suspension?

My '99 coupe is riding really rough. I had a mechanic check out springs and struts and I was told all is OK. I now feel every bump in the road. What could this be? the rear-end doesn't stay planted on take off, and when I hit a bump it feels like I'm hitting a curb.
SOMEBODY PLEASE HELP ME!!!

Dumb question but how much air do you have in the tires? I run about 30lbs.

Did this just start doing this or did it always do it?

Do you have ride adjustable suspension?

Also have you bounced the rear to see if the shocks will stroke?

Depending on Air Tepmature, My tires will hold at 29psi-32psi.
I Have the 3-way Ride adjustible F45 Suspension and the System works properly,( I normally keep it on tour mode and when I switch to sport or perf mode ride quality changes like it should).
I have Pushed down on every part of the car to make sure that the shocks were working properly and they seem to be.
This problem started happening about a month ago and it has gotten progressively worse and I can't figure out what is causing this problem so I can't find a solution.
Hopefully somebody can help me.
Thank you

Just a guess but it happened to my 98 vert. Check the bushings for the rear spring. These are the bushings that the "lowering bolts" go through. There is a pad on the bottom and 2 bushings on the top of the lowering bolt. My $.02.

Good Luck!
