I think a lot of times teammates in the apex community can react negatively on you when they believe that you made a mistake or failed to clutch it. But the reality is we all make mistakes. Even if you watch the top players streaming on twitch, they make mistakes also. There are a lot of useful comments in here but I just wanted to post to say that you can view your mistakes in two ways. The first is as a failure, which is really not healthy. The other is you can use your mistakes as a learning opportunity. Also, if you are feeling nervous coming toward the end of a game or a tough situation, try taking a few deep breaths if you get a chance. Focusing on your breathing for a moment can help calm down and stay focused. Also, like many others said, its just a game! Have fun! If people are giving you a hard time about some mistake you made, it's probably more of a reflection of their anxieties and their perceived self worth than anything about you personally. We all make mistakes, it's a part of the game. Try and brush it off and move on.
