In late February, the day before the World Championship sprint in Trondheim, Svahn fell unhappily during a training session.
A concussion was confirmed and Svahn was forced to travel home to Sweden.
I was very bad then. I slept a lot and was very isolated at home, says the skiing star at a press conference during the Swedish Olympic Committee's Olympic Games camp on Crete.
Back in Sweden, Svahn lived in a dark and dimly lit room to get rest. After that, she gradually took the steps in the so-called "brain staircase".
It becomes special, you go from being in the best shape of your life to having to get through a day. It was two extremes of a world, says the 25-year-old.
I maybe felt so bad mentally that I didn't feel bad about it.
Barely three months after the crash, Svahn tells that she also got other injuries than the one in the head.
I have a neck injury that I'm handling. But we have good control over it, we've investigated it well. But it's often a follow-up effect when you get quite a big trauma to the head.
The skiing star is not in full training but is doing rehab in the gym – where she has the company of her best friend Frida Karlsson.
Our strength is that we're very good at helping each other forward, says Svahn.
