What is the best approach to this situation? So I am still learning chess and I have a lot of trouble in these situations. Please help me with what to do in the next few turns.
You are a queen and a piece down. Your position is completely hopeless. Your best move here is to resign the game.
It's not clear how well your opponent has played to reach this position but you have clearly played very badly indeed. An opponent who was good enough to reach this position is going to finish you off very quickly regardless of what you do.
As a beginner you need to start by learning about opening principles, tactics and simple endgames. If you use the search function in this forum you will find many questions and answers that can help you with these.
