My positioning is soooooo bad man

This is half question half rant

I've started playing apex very recently. Only been about 2 days now, and I can't help but push, find myself between 3 enemies in the open and die.

I'm trying so hard man but the only br I played was fortnite and in that you just push, create your own cover and boxfight people to death.

I'm so so bad at this man. Except for one game, I died this way in allll the rest of my games today. I would push, find myself in between 3 diff people and die instantly.

I guess it doesn't help that I'm playing octane lmao.

I guess my question is, HOW TO BE MORE MINDFUL OF COVER AND WHATS A GOOD POSITION WHILE ENGAGING IN A FIGHT? How to not be a brainless ape. I've never had to have so much spatial awareness before this shit is hard hard.

Edit: Also I don't know the map, I guess that plays a huge factor too
