Hi @Molliex  and welcome to the forums.  It's great that you've found us.  And brave of you to share openly about what you're going through.  So glad to see you've already found a crew of supportive people here and good suggestions of self-care activities.  I've been plagued by what I call 'cyclic thinking' and obsessing on 'what if's' for many years and now have quite a few things in my 'tool box' that I can do to break out of it sometimes.  There's a thread called Coping Box that you might find helpful where I posted my list.  Here's the link  https://saneforums.org/t5/Looking-after-ourselves/Coping-Box/td-p/20101/page/13

Hope you have a peaceful day.
