try and get used to it once you go keyboard and mouse you never go back
There is a reason online FPS never let PC play with console players. Controllers are horrible for FPS games. Getting "good" with one would be like training to run with your legs broken. Painful and at the end of the day you still wouldn't be able to win a race.
Keep practicing. I'm way better with a controller then a mouse. Also adjust the look sensitivity start low and move up until it's well above average. If you can master that you'll have a huge advantage
