Hi, I'm a 25yo female and recently I've been thinking a lot about time, meaning of life etc. I have a good job and home, but still struggling with thoughts.

1. I live in Canada, and the season is changing from fall to winter right now. Winters are very long here, and I feel very depressed at the thought of being in frozen, dead, colourless, arctic for the next 6 months. I'm a gardener and lover of the outdoors, but winter is hard. And no, I really don't like winter sports. Any thoughts on how to combat these thoughts?
2. I've become very jealous of people in warm climates all of a sudden. I can't get up and move anytime soon, stuck in Canadian winters. But I get in these really toxic, low moods when I think about how people in Florida are just sitting by the ocean when I'm stuck in -30C.
3. Canadian summers are super beautiful, but short. So, I try to "maximize" my outdoor time, but then it stresses me out all summer and ruins it. My job is inside on a computer all day so my thought process is like "wow, look it's sunny out. I need to eat dinner as quickly as possible and go outside because the warm weather is only here for a bit". And then I can't relax outside - it feels like I always have to be doing something productive. And it just gets ruined haha...

I totally realize these are silly, toxic thoughts, but no matter how much I tell myself that, I can't get out out of the thinking patterns. It ruins my mood a lot. And then I feel mad when the sun is out during the work day because I'm not "allowed" to get enjoy it, I have to work and make money just to live.

I would love some advice on dealing with jealousy, all the "what ifs" and silly thoughts in my head. Thanks in advance!
