Why is it that when something pushes/pulls on me, I feel acceleration, but I don’t feel acceleration from the earth’s gravity? I feel a force pushing upward on me, but I don’t feel a downward force.

You have encountered something that Einstein also noticed. This is part of the foundation of general relativity. In unintuitively tells us that gravity is *not* a force. Rather, gravity is the curvature if spacetime. To maintain a constant position in space while moving through time, you need to accelerate away from nearby masses.
So, you are actually accelerating upwards, and there is no force pushing you downwards.
