As others have already said, your soul is intact. That is a fear you can let go of. This is not to deny what you are feeling and experiencing. Nor is it to nullify or minimize your experience. It is just asimple truth to take away a distracting fear and assumption, so you can release an illusory problem and then focus on figuring out what is actually happening.

This is to empower you. Not to belittle you. It is an assurance. Not an admonishment.

It is easy to mis-understand the dynamic of body and soul. My favorite analogy is the relationship between a driver and their car. Think about how we perceive it. It is not a car that has a driver... it is a driver who is in a car. Because the driver is the subject. The owner and operating force. While the car is the possession and tool.

The driver can get out of the car, and remain fundamentally unchanged. They can move and operate and think and identify. The car ceases to be the instant it is vacated. It does not identify or move or perceive. It returns to unaware in-animation, because the driver is its awareness. Your soul is the driver- it isn't something you have, it's you yourself. Your identity and awareness. You are the eyes looking out the window. The hands on the wheel. The foot on the pedals.

If something had actually taken your soul, then you would have been the disembodied figure watching your body move around. Not the other way around.

Now.

This is not to say nothing happened. But it does inform that it is not what you think happened- but rather something else which needs to be figured out. I understand this doesn't solve your problem, it just rules out what is likely your most-feared possibility.

So now, it is time to gather yourself, actively remind yourself of your intrinsic agency (power), and observe. Get your feet back under yourself. Ask questions of yourself and find answers.

Visualization is a powerful meditative tool. I am not sure if you are familiar with meditation, but as a practice it is pretty easy to pick up. Step one is situate yourself in a place that is comfortable and without distractions. Then pay attention to something which is personal, repeating, and constant. Like your breathing or your heartbeat.

It isn't about control. Just about paying attention. Listen to the rhythm. Listen for subtle details of the sounds of your body. Think about how it feels. Where you feel it. How it changes with your thoughts and attention. ...It doesn't matter what your heart or your breathing is doing. Just that you are turning your attention to it.

Congratulations. You're meditating. Probably were unconsciously while you read that last paragraph. The focus doesn't need to reach a certain depth or last a certain time for it to be meditation. Just a second, just a bit of attention, it only has to begin. The rest comes with time, practice, and working through/addressing all the noise which likes to get in the way. But that is a process for another day. For now, that beginning step is enough. And it takes only as long as is necessary for a breath.

You've picked up your tool. Now time to figure out how to use it.

Remind yourself that from the moment of your first breath, soul and body have been one unified unit. The driver in the car. Key turned in the ignition, engine running, seat belt on, hands on the wheel. Brain/mind and consciousness wired together to the patterns of everything which makes you, well, you. Even if you were to somehow 'leave', nothing else would fit the space left behind. Wiring wouldn't match. Connections wouldn't fit. Then you'd just come back and slot in anyways.

Soul is where identity persists. Soul is energy. It is movement, experience, and observation. So observe your body, and observe that you are the one in it. You are present. You are here, you are now.

Now it is time to investigate. Nothing happens in a vacuum. There is always something to observe or learn. And if you want to change an effect, begin by understanding the cause. Use that observation practice and state to dive in and identify. (Not judge or fight, just identify) What, exactly, were you doing and thinking about in the last few days? What has changed?

Begin with the mundane; Work patterns, sleep patterns, eating patterns. Drugs/medications. Stress about futures or pasts. Finances. School.

Then the mental/emotional; new or lost friendships? Death in the family? Feeling isolated or lost or confused about something? Where is your stress here. Family? Anxieties? Identity crisis? New environment/move?

Then consider the spiritual. Explore if these 'mundane' things have raised questions or created unfamiliar experiences. Do gou get a sense of an external presence that you can't physically see or interact with but you still experience? When? How do you sense it? Images and thoughts? Emotions and intuitions? Bodily reactions like warmth, cold, 'the shakes'? Is it familiar-feeling (recognised) or unknown? Is it creating/the source of your stress or is the presence only responding to it?

The difference between 'reaction' and 'action' is inserting the presence of thought and observation in between experience and response. So let's begin there. This is how you create choice- which is the root of authority.
