The car loses power when the heat or A/C is turned on

So maybe a month ago the A/C was working fine then I stopped at the store and it just stop running, was no longer blowing cold but still ran.
When you hook a gauge to the high press for the Freon, it goes from empty (white) to over filled (red) to full (green).
Now when you get to turn the A/C or heat on you'll feel the engine vibrate while the engine quite down like it's losing power.
