I am heinously bad at shooters

Idk much about guns, the stats of them, can’t aim to save my life, etc.
My long distance guy loves borderlands and I agreed to play w him and got the game but ohh my god I'm so bad at it, I feel overwhelmed with how much is going on and items to choose from, hes played it a lot and already knows everything so he ends up way ahead of me before realizing which makes me feel rushed and he kinda just assumes I know what to do 😭 also there was no game tutorial?

Anyways he IS pretty patient I feel (esp compared to my ex) and laughed with me for the most part but I can also tell he got a bit frustrated at times when I was struggling with more obvious solutions to things.

Just feeling a lil bit embarassed and silly at the fact I’m doing so bad at it so far wasn’t sure if yall had any tips. Other than the fact I’m doing terrible I’m having a lot of fun playing it haha
