Is it ok to struggle in the beginning?

I bought Frostpunk on the PS5 and played like 2-3 hours of it, restarting the tutorial because I had lots of sick people and not enough food to feed the population. On my second attempt it went well until I send a scout team and returned with new people only to realize that I didn't have enough homes for them and my wood supply is dry. I'm again lacking in coal and food, I'm sending in workers to gather coal but It's very cold at the moment and they're getting sick, to which I don't have enough medical buildings to trick them. Is this like normal to "get through the hard times" until the things calm down or did I fuck up and have to restart the game?
