No clue what to do
Well, this may sound harsh or trolling, but I think it's because you don't really look at the board. Or rather, you don't see the board in spite of looking. Everyone goes through it in their earlier stages, but the best way to overcome it is to play longer games, even with somebody who will talk to you about every move as you play them. Daily chess is the best for this. Although, I think you have guessed this.
I'll challenge you to a multi-day game, multiple ones if you like. In the game, I would like you to tell me what it is you think before and after you play a move, and I will tell you what I think before and after I play a move. And we will do the same to each other. I actually need to do a bit of this myself, I'm slacking off on my planning.
As for tactics and lessons, just keep doing them. Eventually you'll see an impact and it will snowball from there.
Also, don't play 5 or 10 min games. Play 30 min games. I have noticed you timeout a fair bit in your games, which shows you are trying to think things through, but due to a lack of positional and tactical knowledge, and opening theory, there just isn't enough time to accomplish enough.

Um, Diakonia, your suggested alternative on move 8 is 0-0. Which loses the rook.
Instead, 8.Bg5! h6 9.Bc2 and I like white due to his development lead, even though he is down a pawn.

Thanks for catching that. My apologies to the OP. Thats what i get for trying to do this at work.
After the opponent moves, there will be newly attacked squares/pieces. Find them. These are the direct threats.
After the opponent moves, there will be newly undefended squares/pieces. Find them. Sometimes you can win something right away.
For your candidate move, visualize it, find the squares/pieces it will no longer defend. Check if your opponent can exploit this.

After the opponent moves, find 1.which pieces are undefended in his position. (Not newly undefended as above, but pieces which have no defenders at all.) Find 2.all moves that you can play that put the opponent in check. Find 3.all moves that are captures. Try to find a sequence of moves that combines these 3 where you end up winning material. If one sequence of moves looks promising, but doesn't quite work, try changing the move order.
For your candidate move, visualize it as if it's already been made, and now for your opponent, find YOUR 1.undefended pieces, 2,the moves YOUR king is vulnerable to check, 3.the captures your opponent has. Can your opponent use some sequence of these, after your candidate move is played, to win material?

This is basic analysis. It seems very hard at first, but because positions change so slowly, updating your list of undefended pieces and moves that give check is not hard. Also it eventually becomes a habit and you will do these things automatically (at least for 1 move deep anyway).
Play time controls that are slow enough that you're able to build these good analysis habits. Not losing pieces for no reason (and capturing free pieces when offered) is worth many 100s of rating points.

There's a lot of good advice here. Slower time controls. Opening theory plus tactics. Sound opening fundamentals, such as controlling the center, developing pieces in sequence, early castling, all come before memorizing openings. As much as I love the Tactics Training, I also would advise books, for the time being, with no time pressure. Like so many things, chess is about a firm grasp of the fundamentals in the beginning. Forks, pins, etc. are fairly easy to grasp. Patience and diligence. I teach K-5, and it's amazing how fast many of their games develop. Good luck.
