Hello Hazmatac,
You got a wonderful answer from Stefan, I see.
@ Stefan: thank you.
Meanwhile, I was writing my reaction and I will still post it here. At least you will feel supported, I hope.
Sounds like you meet the fact, that the mind has always been functioning in a certain way, and you never realised or thought that it could function in an other way. Is that right?
If so, that will be shocking. Like you realise that you are not as you always thought you were.
That is O.K. Just allow it to be as it is now.
Finding that you do not (or did not) know who you are can feel like depersonalisation.
It is wise to look, off the cushion, if there is a reason for depersonalisation in the psychological sense: Could there be a reason - clear, and right in front of your nose - why you do not want to be where you are. In terms of where you llive, in terms of what you do daily. In other words: Are you safe, physically?
On the other hand, a basic saying in buddhism is: "There is no self". I have had moments on the cushion, that I felt as someone else, or in a situation that I never was in. The way I understand vipassana meditation is that it is about awareness and how you carry your awareness / relate to your awareness. It is hardly about the things that you are aware about.
(I must say, I love to talk about unusual things that happened on the cushion with my wife. She has a very broad knowledge of life and the psyche. So she might give me comments like things symbolising such-and-such, or connecting to our friend or relative so-and-so.)
. . . life force being cut off . . . do you feel that literally, like a knife cutting under your feet or buttocks? Or is it a figure of speech?
I do not understand what you mean by: "making me feel bad, due to the awareness". Do you feel that you are a bad person? Or do you mean it is a very unpleasant feeling? And I do not understand the role or awareness here.
You meet things that are very unusual for you. One of the options people have in such a situation is going insane - you have seen that right, in my opinion. In what you describe, I do not see that you are going insane. You are dealing with it in a healthy way. You are asking advice, hearing reports, considering going to a meditation centre - all very healthy.
Please do not make this the centre of you attention all the time. It is good to have work, family or chores of daily life that take your attention. Walking and actively looking around. A teacher of mine would say: "If you have your hand 20 inches away from you, you can look at it. If you have your hand 2 inches from your face, you cannot look at it. Do not dive into the experiences that you have. Just be aware of them, from a distance."
In my opinion, it could maybe help to meditate in a group because you share energy among one another. You process things of others that you con process better than them and they process things in you that you cannot process. (If there is no-one that can handle your things, than they might throw you out. Nothing dramatic.) (I am not really sure if it works so, and it might differ per group.)
Your question is in fact, if you are doing something wrong. I do not know, because I do not know your practice. And probably my knowledge is not broad enough to answer that question. Maybe you posted earlier what you are doing and I forgot. (My memory is not what it used to be, if remember well.

)
Be well,
Quardamon
