One way to attack it is logically. What is an opponent really thinking when you make mistakes? It's usually something like "nice free punish" in my experience, or they think about what a good job they did lol. Most people are often thinking of themselves more than their opponents in a match. In addition, are your own worries fair to yourself? Do you think everyone plays perfectly all of the time and you hold yourself to a realistic standard? Do you think there are really NO older players that haven't gone 0-2 for longer or started later and gone 0-2 for a while? The main thing is with this is to give yourself contrast and to see other people as being fair to you. Think of your concerns as if your friend had them. How would you comfort a good friend who felt self-conscious about their play, and how would you get them to focus more on the game instead?
Another good question to ask yourself is where do these thoughts and feelings come from? Asking "why" more and more and getting deeper will eventually get you in touch with root causes and thoughts/feelings you can address as well as pain you can accept before working to change. It can also help to ask "what would my ideal self think/do?" and see how it compares. Success is not just NOT doing something bad, but also doing something good and building good habits. You need both, and need to keep reinforcing those habits daily. It's a practice like Melee training.
That's a pretty good starting point and it worked well for me in addition to other things I did mentally and physically, such as meditation and exercise. Hope it helps =)
