I have reviewed your chess.com’s profile and watched some of your chess games. There are many areas where immediate improvement is needed.

Before going to my analysis, let’s go through from one of your recent chess game.
Opening Suggestion:
In many of your chess games, you are not controlling the center and you are not giving the importance of central pawns.
Please remember that Philidor’s famous saying about pawns.:
Pawns are soul of chess.
In above game, on move 6 you exchanged your central d pawn for his side pawn, I know that at that time you do not have much choice, but please remember that central pawns like e4 and d4 are most powerful pawns in chess.
In the opening, on move 3 when black played d6 which is called philidor defense, you have a advantage by exchanging your e pawn and exchanging queen and stopping black’s king for castling.
If your opponent’s king in the center and you have castled king, that’s one of advantage which can be converted into win.
In order to convert this advantage into win, you need to master two skills, one is your piece development and second is attacking skill.
Please do find an opening repertoire, and play according to opening theory and plans, just playing without learning will not improve your chess game.
With white pieces, play Bishop opening and against 1.e4 play Scandinavian Defense.

Middle Game Suggestion:
What is a value of pawn in your mind? If its just a pawn to be sacrificed, then you need to update database of your mind.
In my mind I look at every pawn as a queen.
Now You should learn how to create a weakness in your opponent’s camp and how to play pawn structures.
Endgame Suggestion:
In the endgame, you have only two goals, one is to create more weakness, and second is to create a passed pawn.
Conclusion:
In conclusion, try to learn or create opening repertoire, in the middlegame, learn pawn structures, and in the endgame, learn how to create a passed pawn.
