I only played 2 games since last year lol.
I Can't Play Without Blundering

Join the crowd of bumblers and blunderers; there is no cosmic reason that you should be exempt from the pain of bad moves.

Thanks for the help. I'm not blundering as much for some reason when I slow down but I still throw away games from them. It just seems like too many games are lost from simple tactics and there just isn't much room for playing.
You must always have focus. Before you make a move check if there is a tactical drawback. For example when you move your queen, check if you are free from being forked or being pin. Also always scan the whole board to see the positioning of the pieces. Sometimes we have tendency to only look at the part of the board are taking place. For example your opponent move his queen to the left side to attack your pieces there, you have a tendency to only look at that side without noticing that your pieces on the right side is under attack from your opponent's queen.
Thanks for that advice. I have no problem focusing if there's 45 min/game or more. But I blundered away two rapid games today knowing that if I took time to properly evaluate the position I'd lose on time. I'm trying to do patterns videos/tactics problems/tactics books to speed things up and it has had some effect.

Play longer games, and before you do a move that you think is correct check one more time for possible threats.

You also need to learn time management. Maybe you are not yet used to rapid format. Solve easy problems for pattern recognition. Solve harder problems for calculation improvement.
For every move, look for "Check, Capture, Threat" in that order. Before making a move, observe if the opponents has "Check, Capture, Threat" afterward. The hierarchy of forcing moves really helped me. I wish I remember the article. It will be the hardest to recognize every threat your opponent has, but every possible check or capture he has at his disposal can be evaluated in not more than several seconds. Blunders are only blunders, most of the time, because your opponent can Check, or Capture something after your move. Things like knight forks and discovered attacks and pins are annoying, and are harder to see "threats" but, months of solving tactical puzzles over and over helps. Sure, it's not a day at the beach, but it helps.

Look at this situation from the opponent's point of view----by blundering you are allowing us poor patzers to win a game from time to time. You are doing a good deed for your opponents! Nobody loves people who are perfect.

I only play nothing less than 15 minutes games. I consider blitzes non tactical, blunder prone and perhaps only suited for highly rated players (2000+) who already have a good grasp of the game on a slower time controls and are just doing blitzes for fun or merely a mind aerobics. Longer time controls gives me the pleasures of the game regardless of outcome. I think my worst streak is 1-11 and mostly to players with a much lower ratings. In any form of competition, you need to learn from your defeats to become better and be the best.

Two things:
1) Even GMs feel this way. I recall watching Kasparov many years ago discuss a move he made in a game. I can't remember if it was against Karpov or Short, since I lived in England at the time and both matches were covered on TV. But Kasparov had moved a pawn so as to let his opponent permanently block a diagonal. And he acted as though he'd hung a queen--he just could not believe he'd been that stupid! Even though I couldn't even really tell what he was talking about, but he considered it a horrible blunder. So I don't think this feeling ever goes away.
2) As others have said, play slower. Dan Heisman is a well-known coach around here, and he says that even 30 minutes is too fast for learning.
Do you expect to improve playing blitz?
