Hey, I don't know how helpful I'll be but I had a couple of thoughts. First of all I thought your 1140 blitz rating in 2-3 months is very good improvement, tbh. Like I was not at that level yet after even half a year. Plus it sounds like you have a good practice of studying, which is great.
How do I break losing streaks?

But have you tried some longer time controls? Seems you play 3 min which is quite short and harder to break habits and focus on specific areas. (Don't look at me, I play a lot of 3 min games for fun...) Also, I don't see a lot of analysis reports for your games. Maybe it would help to analyze your games and especially the mistakes, so you don't repeat them. I started doing that a bit more lately (cuz I've also been feeling stuck) and I do think it helps me to be more conscious, like in certain positions I find myself more alert to look for things so I don't repeat the mistakes I often make.

Stop thinking about your rating and play.
I played chess more than a quarter century before I had a rating.

Yeah that's the advice I ended up getting from most. I'll start playing some games with longer time controls. And I do analyse my games, maybe not as much as I should but I still do pretty often. I found that I'm making blunders due to miscalculations and time crunches. Thank you for your response !!
You won't improve playing Blitz. If you are serious about improving, play slow games.
I see. By slow games you mean 10 min rapid or above right?

I was just kidding. However, the advice of slower games is key. As ur studying books/videos, etc, playing slow games gives u enough time to think about what ur learning and thinking about how to put those lessons into ur plans. Playing too fast won't allow u enough time to think so u end up playing what ur used to. U just end up doing the same mistakes over and over, just firmly implanting the wrong chess habits into ur thinking.

Correct.
I played Daily (three days per move) for improvement.

I played 4 day games. It didn't get me anywhere. I say, play as fast as you can. Use the flash card technique. https://en.wikipedia.org/wiki/Leitner_system
Look it up.
... and that's why you're already a 900 player while I'm only 2350, yes?

WHAT!? As a person who plays a lot of 1 min (another "fun" tc), I must say I don't think play as fast as you can is a very efficient way to improve

Second when you start suspecting a bad streak go puzzle battle and play until you explode 🤯

Ah. thank you. I'm starting to get used to rapid games and I already see why theyre better for improving. I can think and improve my technique rather than play sloppy moves with little time to think.
I'll likely try daily games soon too but I'm not sure if I can commit to something a long as 3 days per move.
Thank you for your advice though.

A coach defo helps, thats most people's favourite way of rapidly improving but I'm only 14 years old and 50-150 bucks for an hour lesson is a hefty price to pay.
Maybe when im older

Start winning. I hope that helps, good luck.
If winning doesn't work out, try whining.

@Khoaque -
Here's an example of the sort of accurate play (99.4% CAPS accuracy) that you can get in Daily.
My game is the second one in the thread.

You should do a chessables course on your ego.
Confidence is a great asset, if it's justified.
If it's justified.
I have been playing actively for about 2-3 months now. I am rated about 1140, peaking around 1200. I am an extremely weak player considering I have been playing for months. I am trying to improve, but to no avail. There is one thing holding me back, and that's losing streaks.
Every time I improve my rating by about anywhere from 20 to 80 points, I get hit with losing streaks that bring be back or often way below where I started When the losing streaks occur, it doesn't really matter if the opponent has a higher ELO or not.
I have studied openings and traps, done hundreds of puzzles on Lichess, but no matter what I do to improve whenever I go back to Chess.com and play I always get cursed with losing streaks.
I'm mainly wondering, does this occur because my skill has gradually gotten worse? or is it just a mental/psychological issue.
It's extremely frustrating and I am quite close to just closing my account and quitting Chess.
If anyone has been stuck at a certain rating for a period of time and managed to succeed in improving, I would love to hear your advice/criticism
Thank you!
