I don't like doomposting. Venting has a place, and sure even doomposting, but in the end I'd argue it needs to become something and it needs to become something that you will find meaningful.
Or not, it is your life, and it is your choice what to make of it.
But movement is better than stagnation. Like how you deal with trauma responses: food, movement, touch.
Eat. Move both mentally and physically within your capability, shake it out, decide on what next. Pet a cat or hug a partner.
