I'm playing poker now for six month and have already lost approx. 1200$. But, hey, as everybody here, I love this game and don't want to abandon it only because I'm losing.

Dont take this the wrong way but I would consider dropping down to .50/1.00 or 1/2. Why make the learning period more expensive than it has to be. Work your way up as your roll increases from the winnings.
You see your mistake by not folding the flop so you are going in the right direction.

In this situation you will get NO-ONE at 2/4 to laydown QQ here. Save your money, fold the flop.

You have 3 outs at best in this situation, and you need to save any type of move like this for times when the river could often bail you out. Plays like this are profitable only if you expect the bettor to make a tough laydown(they won't) and you have enough outs to win even some of the time you're called.

I second (third, whichever) the suggestion to move down in limits.
