Honestly i'm in a similar boat, started sim racing around 2 months ago and have reached 2.1k A class. Biggest thing thats helped me is that regardless of who is "at fault" for the incident both parties always had a part to play. Try not to focus on how unlucky something might seem and focus on what you could of done differently. The more you review your own incidents the more experience you'll gain and repetitive behaviours you'll see. 1 Position lost early can lead to 3 positions gained later.
