Anything that helps me escape into a world of fantasy and not remind me of real life and stupid people. World-building, pre-2008 games, pre-2008 movies, classic books, manga, etc, especially fantasy and isekai. I prefer older stuff as I find most modern stuff is just too vulgar and degenerate. With world-building, I can spend hours in pure bliss just in my own little fantasy world, creating new stories or researching things to add to my world. I usually cycle through different media, so I'm not bored of one thing and can constantly stay comfy. Right now, I'm going through a manga binge. I do have comfy days or routines for different times of the year. For example, I have a LotR EE marathon every Christmas, I find myself playing strategy games like Anno 1404 a lot more during winter as well.
I also love gardening, it helps me feel like I at least have a little bit of control over something and mould a little part of the real world to my liking. Plus, it is so rewarding to actually put effort into something and actually gain from it, not like the drudgery of a dead-end job. I know it's cliche, but there is honestly something about sitting down in the garden on a quiet hot summers day, putting on some classic music (imagine Joe Hisaishi's One Summer's Day), glass of cold juice in hand, and being surrounded by your growing flowers and vegetables, with butterflies fluttering around and the scent of cut grass. I am already planning next year's garden, building raised beds to make it easier to weed and harvest, as well as planting a dwarf sweet cherry tree so I can have free fresh fruit in a few years.
I love walking, going through country and forest parks, or up into the mountains, or along quiet coastal paths. Especially during weekdays when there are hardly anyone about. Get a good day, even in winter, with fresh air and a comfortable pace, just re-energises me and helps me snap out of any spiral I'm going though. It also allows me to immerse in my own little world, like "here I am, a medieval monk going on my pilgrimage to the top of this Holy Mountain". Gives me ideas for my world-building and helps me put some parts of it into perspective to make it a bit more realistic. I'm not particularly fussed about my health, but another good thing about spending a day walking is I've exercised! Like gardening, after a long day walking, sitting down on an isolated bench with some picnic or takeaway fish and chips and watching the sun set over the harbour and beach is very comfy and rewarding.
Food is indeed another great comfort. I've found that an all-greasy/sweet meal just makes me feel worse after a while, so I like to have a nice balanced meal. And by balanced, I don't mean nutritionally balanced, I'm still going to enjoy "unhealthy" food, but it's going to be a bit more varied than just processed fat and sugar. Like having a good mash and steak, or a cheeseburger and fries, or spaghetti and meatballs smothered in cheese, followed by brownie and ice cream or cheesecake or apple tart, rather than just stuffing myself full of doritos and mountain dew. I don't drink alcohol, too poor and too afraid of becoming an alcoholic, but I do indulge in flavourful drinks like a malt milkshakes and fruit smoothies. Takeaway is fine once in a while, but I prefer to make my own food. Not only does it reassure me of the ingredients, but I think putting a little bit of effort in makes the food all the more satisfying.
So I do a lot of comfy things. I need a lot of comfy things to get me through this life. Best thing about these hobbies is that they are relatively cheap and you can spend hours on them at a time if you want.https://www.youtube.com/watch?v=TK1Ij_-mank
