Massive losing streak - asking for advice for future

I empathize with the anger after I lose or make a blunder... Best advice I can give on that would to "schedule" yourself games whenever you know you can give them your full focus. Im at the point where I only try to play a few rated games a day to make sure I can learn from them. If you find yourself wanting to play chess without the rating stress, you can always make a lichess account or play anonymous/ unrated games.

Chess rating can be a roller coaster. When you suffer 3 consecutive losses, call it a day. Play the next day.

If you loose too many points and get frustrated, you start a new game hoping to win your rating back. Because you are already angry for having lost a number of times and because you are being paired with people far below your real ranking, you pay too little attention to the game and you loose more. Then you get even angrier and more frustrated and want to avenge your lost rating points even more...
It is a vicious circle. Don't follow this pattern.
What seems to be working best for me is just quitting for the day, having a good night of sleep and trying again the next day with better (not so vengeful) attitude. Rebuilding rating usually takes more time than loosing it, but eventually it works.

This is something that a lot of people here experienced.
I can only tell you what I often do when I think I simply cannot play chess.
1. Stop playing for a while. It can be one week, two, or perhaps longer. If chess is not something enjoyable, try to find something else that will bring joy in your life (for example, studying chess is an option).
2. Focus on studying something that you think will help you. How to defend is a topic that people usually do not pay much attention. Most people like to make puzzles, and they are certainly important, but undeveloped defensive skills are really bad. You can be able to mate in 4 moves but regularly miss your opponent mate in one.
3. Before you go back to play, write down on a piece of paper how many games you plan to play, and commit yourself to this number and to analyzing every game. Write down, really, don't trust yourself! At least try to find out which was the first blunder in your game. If you do this, you are not really trying to improve immediately your rating, but you are trying to improve your game. There is a difference between both. You can fall into a trap in the opening (GM can fall into such traps sometimes against a 1500 online player), and this is annoying but not the end of the world - IF you learn something from this game.
4. Commit yourself to a certain number of games. If blitz or 10 minutes rapid: five games. If longer games: 1 or 2.
5. There is a podcast where a player explains how he got 2100 in blitz in chess.com in four years. He basically watched John Bartholomew's series Climbing the Rating Ladder (and other guys). I knew this series, but I didn't know that this could be so effective (passive learning!), but it seems that it works. In my case, I deleted several opening books in Chessable and began to watch these videos.
After I did a break from chess I was doing what I wrote before, and when I came back to the game I won easily 150 points! I found my 1500 opponents incredibly weak!! Then I forgot my whole new approach and began to play like a madman again, with no analysis, like a junky, and I drop all the points again.
I am trying to restart again with my previous good chess habits.
Anyway, good luck with your journey and keep us updated.
