Bad things happen. Relax. It will get better
But if you have done it enough times. Even in this state of essentially insanity, you on some level can remember that
These things happen.
It has happened before - it will most likely happen again
And this time
It is temporary
It will end, and though it seems like it's been more than half of forever and you can't even remember exactly what it's like to be normal
And you can't imagine ever being normal again
You still know that it will eventually
You know that there is nothing you can do to accelerate that process. You just have to wait.
It feels bad now, and it will feel bad, physically, mentally, and while you can't change that
You can focus on being calm. It is unpleasant but it is not the end of life, it is tolerable.
You accept it, remain as calm as you can in a buzzy jumpy loud colorful insanity - on one level it is impossible, but on another level there can be a kind of calm in waiting, in knowing it is temporary.
Everyone has experienced both good and bad feelings. The bad ones are like the bad parts of the drug. It has happened before. It will again. And this time it's temporary. Accept it. Calm down. Things will be better eventually.
