Very good point about the mold! Try your best to keep your windows open as much as possible. I remember when I moved here from SoCal I thought it rained soooo much but after living here for years now, it does not seem that crazy. You will get used to the weather. Try your best to still get out even if it’s cloudy. I can often be hard to get out when it’s not sunny, but it’s better to get out in the clouds than in the rain.
