Sounds quite typical, actually

Some suggestions:

Loosen up a bit, for one thing. Play connecting cards (suited or not) from middle position back. Even raise pf with suited connectors; if you're last to act and it's checked to you you can check behind and pick up a draw for free on the turn. Play big connectors from any position, as well as any pair. Jacks or smaller you want to hit your set, since those hands don't hold up in multi-way pots.

With AA or KK remember that if you're getting 6 way action after the flop and only win 1 out of 3 times in that situation, you're getting a HUGE profit in the long run. Jam the pot with as many people in as possible.

Almost never bluff, and don't try to bet people out of the pot. If they have a piece of it they'll be in to the river.

When you do hit your hand:
Value bet. Value bet. Value bet.
