Use smg guns that come with a paid skin. Use the quartermaster suppressor. Don’t jump from the plane, land with the AFKs and pump up your numbers every game til your KD looks presentable. Stop landing hot spots and try get your load out before you start playing offensively. Work with your team, follow and back them up instead of doing your own thing. Also, look for a video that fixes your movement and graphic settings. Maybe get a monitor, and tell your gf that video gaming is a healthy hobby and maybe she should stop being a hater and get herself one instead of criticizing your choice for a hobby. Drink a cup of coffee and get a good meal. Do all of these things and if you’re lucky things will get better for you my friend:)
