The answer will be different for everyone. Saying, just sit at home is over simplistic because they're actually allowing us to go out to the shops, to see to sick & elderly relatives and for exercise.
The problem is that if we don't do this properly we just offset the worst of the death toll, not prevent it. The simple question to ask yourself when it all feels too much could be "Is going out unnecessarily worth killing for?", as that's what you may be intentionally and unknowingly doing. Then consider that you may not have just one victim, there could be thousands! That's how viral infection works, they spread indiscriminately as fast as they are able, the ONLY way to stop them is to vaccinate (which is not yet possible) or to isolate. We are not currently isolating, just distancing ourselves, so the virus will continue to spread, but massively more slowly and on a much smaller scale, limiting it effects.
I personally can live with the unintended consequences of my actions if they are as a result of necessary actions taken to feed my family, pretty sure how I feel about the risk of the same consequences being multiplied because I didn't follow health advice.
I'm not underplaying how hard this will seem in weeks to come, but remember you ARE saving lives by complying with social distancing, and those lives could include your own grandparents, parents, siblings and even children as well as the families of others, so at least you're not doing it for nothing.
Stay strong, stay safe, stay home.
