Sure you will feel disconnected from people, that's exactly how you were indoctrinated. It's "us" and "them". In the world, but not of the world. "Worldly people", "demonized people" - it's all about disconnection, it's all about other. And when you disagree they just continue the mind control and lack of balance and freedom in your view of humanity.
I believe there are therapists that specialize in this, you should do some research.
What you have to do is rebuild, find positive reinforcement, UNLEARN all the blocks in your mind, interact with humanity freely - learn to trust yourself and your judgements. It takes time, meditate, find yourself, learn yourself and feel comfortable in your boots. After that find some friends that you can trust and just learn to relax and laugh and be free...
