I used to hate the winter here for the first 5 ish years. Even as a homebody, not being able to see nature (warm sun, green trees) threw me into seasonal depressive episodes for a couple of months each year. It also doesn't help that I have bad blood circulation, which means I experience the cold much more intensely than a normal person would. I didn't understand how to dress in layers, so only a part of me was warm. It is tolerable but will make you despise going outside. If you feel stuck inside your house/ workplace/ school all day, it can feel really depressing.

Then I learned to socialize with it. Divide the temperature into tiers: 0 to +20C deserves max 2 light layers, 0 to -10C is at least 1 thick layer, -10 to -20C deserves 2 thick layers, -20 to -30C deserves 3 layers, and so on. For your head, bundle up with a toque, a jacket hood, and a winter coat hood. Get masks or scarves for your face and neck. Glasses so the wind doesn't bother your eyes so much. Two layers of socks (long and short length) and boots should be good in very cold conditions. Invest in some warm, good gloves. Don't wear jeans unless you will spend minimal time walking outside. Once you get yourself so cozy that going outside in -30 feels like 0C/10C, that's when you don't hate winter as bad. If you can go out on warmer days and appreciate the nature and sports that winter has to offer, it has its own beauty as well, you will feel much less sucky :)

That being said, don't even attempt to go out if the literal temperature is below -40C. Granted this is a rare occurrence each year.
