Hi! I'm also a divine! I can relate to this to some extent - I feel just plain wrong and out of place so often, ahh
Definitely seconding the above!! What's comforting to one angel might make another unhappy (especially considering some feel very fondly towards heaven, while others absolutely do not, regardless of status), so it's good to do some healthy introspection and think about what's important to your identity, and what you need to feel at ease.
I'm not fallen, but personally, I love small charms and decorative pieces and things that have holy imagery. I really want a necklace with wings on it, or a statuette of an angel, things like that. They feel really homely and reassuring to me. Also, if you're able to paint or buy decorative lights for your room, they can really make the atmosphere feel more personal and comfy. Maybe you could take a little section of your room and dedicate it to your kintype! Take a corner or a section of a shelf or a container or what have you and fill it with things that make you feel more in tune with yourself, and then you have something to turn to if your feelings get bumpy.
Clothing choices can make a big difference, too! Finding an aesthetic that makes you feel more true to yourself is fun. If you want a more subtle approach to wings, there are lots of neat sweaters and pajamas out there that come with little wings attached! I have a winged kigu for birdkith reasons, and I love it so much. >w<
(Blizzard interjecting here - I think having a cloak or cape to just wear around the house would be sick. Like, it's not perfect, but it's reminiscent enough of the feeling of wings to be comforting, y'know? Plus, I might've worn a similar thing in my memories, so hey, bonus.)
I'd also definitely recommend associating with other divines. There are lots of really lovely angelkin and general divinekin groups (especially on Discord) that accept everyone!! It can feel really fulfilling to be surrounded by people who can empathize, who have gone through similar struggles, and may even have similar memories. They also have a lot of cool ideas for making life a bit more angelic (or demonic, if that's your taste)!
This is a bit long and ramble-y, but I hope it inspires. ^^
