I know that feeling, buddy. I was slightly optimistic too that perhaps Scotland would begin easing things a bit sooner than England are able to but it looks like Sturgeon has gone the other way and pushed things back a bit more. The thing that is getting me through is the knowledge that this is the final push and final "proper" lockdown we're (hopefully) ever going to have to endure again.
We're still just a matter of weeks away from freedom in what has been a year-long battle with this virus. The light is still there at the end of the tunnel.
