My tips:
1) Before you make a move (Even if its to obvious for example a taking a free piece) play the moves that your oponent could play in your head (how could they respond) If there are any checks, captures, or maybe they can attack you in some way.
2) Don't exchange your pieces everytime. If you have the advantage because you have a large attack on his king and then he offers to trade pieces in my opinion you shouldn't accept the trade, because it will reduce the amount of pieces that are attacking or pressuring his king.
3) Take a break from chess. I did this like for 3 or 4 months because I was getting stressed of chess for not improving, I got stuck in this elo too.
I hope this can help you!
I didn't need a coach to improve at chess so I don't think that it is necessary for you to get a coach right now.
I'm 13 so if there are any mistakes in writing I'm sorry!
Also I'm not a native speaker and I'm not using any translator here, lol.
Take care, bye!
