There is one junction on the way to work that always freaks me out. It's too shallow and there is no time to prepare if something wants to come out of it. You know what I learnt? It sounds stupid but I can't control everything. We will always dodge each other on the slip road, there is plenty of room but it might be more uncomfortable than I would like but it's okay.
1. I would look into Buddhism and acceptance. I don't know the exact phrase but basically it helps you chill out. It's NOT about religion. Just accepting some shit is outside of your control.
2. I obsessed about the junction each time. I never thought about the dozens of times that I managed it. Concentrate on the positives. You are doing okay mate.
