your playing the hands way to passivly.
you say you r not one to check and call yet thats exactly what you have done on the two hands.
hand 1:
the only reason why you would consider limping here would be if you didnt wanna commit any chips to the pot before the hand developed.however that argument is only valid with a deep stack but with your stack you should be delighted to commit as many chips as possible to it.
after the flop you have TPTK but the board is scary.
you have a flush draw and a possible str ,yet you still dont bet and giving the villan a free card here is even a bigger mistake than not raising preflop.
the turn is another heart and you still dont bet and you still fail to try to take the pot away or define your hand or get any info about villan ?that is very passive poker.
when you just called preflop with AK,what were hoping to flop?

hand two:
again your going into check calling mode.
you have about 3K left after the flop,ask your self here are you willing to go broke here with one over card on the board?if you answer yes,then you should push here because there is a good chance that villan is just bluffing and he would fold to your push.also a push would make sure that you will see the turn and the river card both which may help you.i think again considering your stack you should deffo gamble here:you have second pair,and a back door nut flush draw+2 other Ks that would more than likely win the hand for you.so this is an easy push on the flop.
but know this that ever time the villan bets and you call ,your giving him the correct odds to draw and making it harder for him to release his hand.
i hope this helps.
