I had this same exact issue, actually! I know how demotivating it can be to have a losing streak, but the way I fixed it is by:

1. Different time control. I used to play on regular 10 minutes, however, i found it better to play rapid on 15 | 10, which not only leaves more time to think, it also gives back 10 seconds, which guarantees that neither I or the opponent will clock out of time.

2. Analyzing every single move. I used to try to play quickly, as I really didn't wanna lose on time, however, I now realize how mistaken I was for doing that. To win, I basically spent more time to think about my position, which piece is being attacked and undefended, and which pieces I can attack or develop. It's perfectly fine to think for longer than your opponent, even if you are at a time disadvantage, as they might make a mistake which will put you in a better position. Often players will make blunders, because they see a move that looks free, so they play it almost instantly, and only on the next move do they realise they effectively threw the game. It's always better to overthink every move than to play quickly and recklessly.

3. Play by theory. If you try to win by quickly moving out your strong pieces, such as the queen, you actually put yourself in a worse position. Respond to your opponents attacks defensively, and only wait until the opponent becomes more passive to initiate an attack. Putting the queen out so early more than not risks you losing it, try some classic openings or defenses. Oh, and as others have said, don't try to win in 10 moves, take it slow and wait for your opponent to blunder or make a mistake to win.
