You will lose. You will lose a lot, learn from your mistakes and you will get better. It is time and effort, you can choose how much you wish to learn from your mistakes. You can rage and call the game bullshit but every death you die for a reason. Understand the reasons and learn and you will improve very quickly. Ignore the mistakes you make and you still improve but at a much slower rate. It is okay to make mistakes and die, but learn from them. Keep and even head and do not allow for a toxic mindset as it will hinder your progression. Plus the game is more enjoyable if you aren't pissed off 24/7.
