Being around kids can be super healing, in my experience. They pick up on things really easily, sadness especially, and won't know how to offer condolences, but they're in the moment with you completely so you're not alone.
I have OCD and grief frazzles/inflames that. I don't always want to or have the energy to address negative feelings, but find there's a compromise between suppressing and losing it when I'm kind of just a kid with myself. They're just there with you, even whilst they're gleefully making a huge mess just for you. I don't know, maybe that makes no sense lol. I just keep my own thoughts company.
And then I play whatever pops up on Youtube when you search "magical library raining ambience" to help me fall asleep or take a sleep vitamin because when I'm sleep deprived... ( ˇ෴ˇ)>⌐■-■
