For me ladder anxiety has always revolved around the mindset of "Look where I am now I don't want to lose that league." However, once you understand that you have to lose to improve, it disappears.
It took a while, but once I hit Diamond as Zerg I actually started to take a serious interest in my replays. I would look at my losses positively and realise that they are simply stepping stones to the next win, the next league, etc.
It really is a matter of "just pressing search". Try to get a feel for how helpful losing is, though. It's the best learning tool in the book.
