How do you know if you're experiencing the dark night of the soul?
You know that you have experienced the dark night of the soul, if at the end of it or shortly afterwards you become enlightened. Then you will know that it was your last depression.
In the process though, you cannot know.
If things are hard for you now, persevere. It’s all temporary even though it may not feel like it. Fear is just fear, anxiety is just anxiety, despair is just despair, those are simply experiences, emotion, nothing else. Your body is fine. It’s a ride. Don’t believe your thoughts. Meditate, practice self-compassion, and if you feel like it, try psychedelics.
Never under any circumstances hurt your body. If the impulses arise, just witness them. It might feel like you’re going crazy, but remember that you never have to act it out, witnessing it is enough.
Don’t suppress your emotion, cry, be angry. Feel it all through, just don’t act.
Stay with it all and good luck!
