Read something that isn't about trans stuff at all, something about dragons usually helps me
Do something with my hands, crafting things, making gifts for the holidays, sewing, crocheting, baking etc
Talk it out with myself, either write it down or legit just say it out loud and vent to myself lol
Make something that I can break, this works a ton legit. I will make something flammable or easily breakable out of cardboard and just go out in the backyard and put it in a fire pit, beat it up.
