Answer: I understand you perfectly. But you are not the only one. It is practically in everyone.
There are people who establish contact with other people easily. For others it is difficult, and there are those who do not feel other people at all. They live by themselves as if there are plants, not people, around them. This is how the Creator created us.
Therefore, you should not compare yourself with others and be offended. It depends on the root of your soul. Developing Kabbalistically, you will discover that everything emerges from this root. The soul has its Reshimo (spiritual gene) that determines absolutely everything in you.
Each of us has his own specific spiritual gene, which is nothing like the others. That is our place in the general system Adam in the common soul. It is only mine, only yours, his, and so on.
This place defines all our properties: physical, biological, genetic, spiritual, whichever. The same place defines our destiny.
If we knew our spiritual gene, its place, and its coordinates in the common soul, we could calculate everything that relates to us. There would then be nothing incomprehensible either in us or in our lives, not in what has happened, is happening, or will happen.
But it is closed for us for the time being. You will attain everything when this revelation will not hinder you in your spiritual development, but will only help.
