How to get out of 1200-1300 elo?

I have been hardstuck at 1200-1300 elo for years now, and I am looking to get out of this plateau and want to improve. Any tips? (ik im nearly 1400 in rapid, its definitely higher than it should be)

Rapid is actually the best way to improve your blitz, assuming you already have good time management. It's difficult to build a more complex tactical eye on fast time controls, so try some rapid practice and attempt to find more complicated tactics than you normally attempt. I see you haven't played rapid since March. If you're worried about your Elo, make a second account where you don't worry about it and try out new ideas.

More broadly, 1200-1400 is where hanging pieces become rare so you'll need to force wins more. Positional play should become a bigger focus as you rank up.

Try to analyze your games and your openings choices to reduce the mistakes, study endgame techniques.

Improving at chess is usually not easy. If you can afford few lessons, I would advise getting a coach. I can teach you how to think during the chess game. After that, your progress is inevitable.

If you can't afford any lessons, here is the excerpt from very good article on how to improve:

Play a lot, analyze your games, and primarily study tactics. Your knowledge of openings, endgame, middlegame, etc. will come from analyzing your games and going over grandmaster games. Only study one of those specific topics if it is clear you are specifically losing because of that topic.
