FFF v1.2,
You'll get over it by getting used to it. Also by realising that it can't actually hurt you - no-one has ever collided with the sky. If it's really bad, and you don't have to be at a certain altitude or fly a very precise heading, just let the aircraft do what it wants. We did that in Southern Germany recently - at 5000 ft, above 3000 ft mountains, with a stonking tailwind and constant up and down drafts. It was easier to let the aircraft climb and descend a bit and wander off heading than keep fighting it, just so long as we made sure we were going in roughly the right direction. But it was exhausting after a while. We didn't particularly like it. And you don't have to like it either, just get used to it. You will, give it time. You don't have to do it all at once. There's a reason why people count flying hours, as some things (not all) are learned simply by being in the air and getting used to the alien environment. This is one of them. Stop worrying.
