for me reversed nine of swords has almost always meant the storm is passing. like you've been in the thick of the worry but you're starting to come up for air

honestly it depends so much on the surrounding cards for me. alone I'd lean toward relief but I always check what's next to it before deciding

wait I love that you called it the 3am anxiety card lol that's exactly it

same thing happened to me a few weeks ago, first reversed pull after months of upright. I took it as permission to finally talk to someone about the thing I'd been spiraling on instead of just sitting with it alone, and that alone helped a lot
