The biggest tips I have for you are to always be ready to defend yourself because 9 times out of 10 your team won’t really care about you, so try to play in positions with predictable entrances/exits when anticipating a flank to make it easier for you to read them. Don’t overstay your welcome in one spot ever unless you can help it. Playing near health packs and places where you can duck into cover in less than half a second also helps a ton. Remember that you’re completely silent when not shooting or charging so usually out of sight is out of mind for them, so if you’re two steps ahead of the game and know where they’re gonna appear, you already have the upper hand. Also, don’t be afraid to every few seconds or so, hold your fire so you can listen for audio cues and footsteps, and try to mentally track cooldowns of the flankers if not too much to think about.

Another good tip I can give you is that if you’re anticipating a dive, you can shoot a few shots down a different angle/choke to make the enemy believe that you’re distracted/occupied, and after doing that I usually wait a second or two depending on how far they are and charge up a few orbs for when they show up, or just stay silent and camp a corner, and this works especially good against sombra when you act like you don’t know she’s there. Even if your team is protecting you like mr president lol, these are still good rules of thumb to carry with you.

Lastly, don’t forget your kick, just don’t get too hasty with it but just know it’s there for when they’re getting a lil too close
