Sorry this happened to you, bud. This whole lockdown is a complete scam. Sweden got away with no lockdown and they did fine. Studies show there is little/no appreciable impact of severity of lockdown on COVID-19 deaths. Don't let people guilt you about trying to go about your life in these ridiculous, completely unscientific times ruled by fear and hysteria.
As for what's going to happen to you. I'm not sure. I really doubt they'd jail you as this is such a minor infraction of the law. There will probably be some deal you can work out.
