Maniacs make me into a donk

It sounds like you need to raise more with medium-strength hands, and by medium-strength, I mean a hand like middle pair with an overcard kicker on the flop. Strangely, you are probably also going too far with a hand like TPTK. You should be raising with middle pair more often than you should be capping with TPTK on the flop. Of course, at some tables, you should consider just calling the flop with TPTK and raising the turn.
