I can't win anymore

I study and play every single day for hours on end, and if I'm not playing chess I'm either going through games in my head or watching videos or reading some of the books I have about it, I love the game so incredibly much but it hurts so much to lose every single time I play even though I study and train for hours every day, I cant seem to get any better I had a period a couple days ago where I was winning multiple games in a row consistently and now I just can't and I don't know why, I don't want to quit I love the game but it feels like the game might not be for me or something I don't know, please help me.

Look at your record over the last few months. Your blitz rating is up by 342 points in the last month. You must have been winning a lot more than you were losing.

Do you review your games? In your last game, you had many chances to bring the game back to equal and you missed all of them.

You're really climbing up the rating ladder faster than allot of players. I think hitting some ceilings that take more time to break through is very normal. I was a 500 3 or 4 months ago, and now I'm 1100 rapids. Every 100 points or so I hit a ceiling that takes up to a week or more to break, then I breeze through, but I just like playing for fun, and I'm not that focused on studying that it ruins the game for me. My suggestion is just have fun playing chess, that's the important part, or else you will lose your love for the game. Getting better is an amazing thing, but it does sound like you need a break to refresh, and try playing 'just for fun' for a few days or a week or two. (Maybe I'm getting you wrong though, I know some people love the game for the studying and improving.)

Hey, don't spend all of your time playing chess. It will wear you out. Plus, gaining rating as fast as you are is a huge achievement for every chess player.
