I'm a new player at valorant so I wanna ask , is is that certain guns pair better with certain character abilities, like if I picked raze should I be using a specific weapon to complement her abilities or is any gun okay as long as I can...

Recently I deranked from Silver to Bronze and my mental is just all over the place, I get tilted so easily for no reason and I feel like I've forgotten how to aim, any tips to improve my mental?
