I’m just so angry. I’m a human pressure cooker. I don’t even know what to do with it
After acknowledging your anger--which you've done here--I would workout. Vent that anger into a brisk walk, jog, or run. Try a meditation app like Headpace. Call a friend. If it's late, try a sleep stories app. Anything but the dark side--the bottle, the fridge, the kissy "friend" guy. Figure out of next actions when you're rested and your emotions have run their course.
