I've tried many defenses to the queen pawn as I've had the same problem. Go with the Slav. It's the best...that's my anyway opinion.
What opening against 1. D4 would be good for me?

If you think that your opponent is too dumb to play 2. d5 then I would recommend the old benoni: 1... c5.
Otherwise, I'd recommend 1... Nf6

Consider the Slav Defense.
When I coached a very successful high school team, the main problem for beginning tournament players playing against 1.d4 was that they frequently played QGD, with 1...d5, 2...e6 and they were not able to get their c8-B, their "Bad Bishop," into the game and did not see a clear way to make threats and launch attacks against White.
To make things a little more straightforward, I taught them the Slav Defense, 1...d5 and 2...c6, where the goal is to get that c8-B to f5 or g4 before ...e6 blocks it in. Then ...Nd7 supports c5, b6, and f6 and Pawn-led counterattacks that usually begin on those squares in usually that preferential order.
That way, my players focused more on getting to a playable middlegame: how to make ...c5, etc. possible, than on mindless book moves.
Note also, that ideas behind The Slav is very similar to the ideas behind The Caro-Kann, 1 e4 c6 2 d4 d5. In fact, against 1 d4 I usually play 1...c6 hoping for 2 e4 d5, transposing to the Caro-Kann.

The chess personality test do you mean this one?

because it is certainly not an accurate representation of your play-style.
After experimenting with it i got the arrow right to the edge of attacking and aggressive and the other two closer to intuitive and emotional. It said i was Capablanca who is a genius i then clicked on a random personality and went back to genius and the bars were at positional and solid and the other two were at intuitive and emotional. My results were closer to Anaconda or Barbarian.

As a d4 player- openings from "best" to "worst" IMO
Nimzo/QID- blacks position is SOLID (so much so that i have switched to the catalan to avoid it)
Ragozin- black is very active, catalan also avoids
Slav (classical>meran) , QGD, Benoni, Benko, stonewall/lenigrad
KID
Classical Dutch
other random opening tries (1... e5?!, 2...e5?!, 1... nc6?!, etc...)

I've tried that twice before and got different results. Tried it again just now and got another result !

Anything, actually. Just play ten games of everything you can imagine, in sequence, and see which you take naturally to. Start with the queen's gambit accepted.

If you've only been playing a year, you might want to stick with a basic QGD. It's sound and straightforward.
The Gruenfeld is not really a defense for first year players. The Nimzo can go off in a lot of different directions depending on White's response.
If you want to keep things even simpler, the Dutch Stonewall is a tough nut to crack and can be played without much preparation. However you do need a plan for the Staunton Gambit (1.d4 f5 2.e4).

just dont do nimzo cause it is extremely complicated (unless your like 2100) just do a old fashioned Benoni

Herk4: Good of you to say. Many people ask advice and never acknowledge the responses.
For the record I started with the King's Indian because Fischer was my hero. I really didn't know enough to play it and I got blown out of my chair the first time a better-booked player wheeled out the Samisch variation against me.
Nonetheless, the KID suited me and most of my opponents didn't know how to to play it anymore than I did. We would just come out swinging and a good time was had by all.
Over time I learned my way around. It was a good experience since the kingside fianchetto plus castling is a standard setup you see all over the place.
Hello
I have played for almost a year now and it is really hard for me to find good defence against 1.d4. As white I really enjoy playing english opening (line where I push e3 and then d4). I also like playing sicilian classical line against 1.e4.
I did that chess personality test and got professional witch recommended both english and sicilian but nothing against 1.d4.
So now when you know my opening style, I would be really happy if someone would recommend openings against 1.d4 that would suit for me. I have already tried grunfeld and nimzo-indian.
