Aircraft landing and wind issues

I am trying to figure out for the life of me why I am 40,000 feet in the air and my BREDOK3D 737-800 is going back and fourth like I am in turbulence the whole time. The wind is so hard up there feels like my aircraft is going to tip to one side and crash then it tips the other way as well it’s like I am stuck in turbulence for 435 NM that’s not realistic. The question is how do I turn down the wind or turbulence. Question: Number 2. When I land it seems my aircraft was to jolt off the runway to the left and it’s like I have no control of it. As I am only using joystick thurstmaster T1600. Any setting I need to turn off or a tutorial video showing me how to do all of this would be great and a link tot hat video. Thnaks a lot and hope to get this resolved asap.

Could this be your issue?
