Hii friends.. I am actually dealing with kundalini syndrome. The problem arouse when i was my mind was unintentionally using the energy to flow from down to up through mental images as was involved deer exercise and yoga..This ultimaty caused me headaches with severe pain in head, disturbed thoughts, poor concentration amd focus. I thought taoism may have some answers to this..could anyone help me out..dealing with it.is like hell..kindly help if you certainly know..#pragma once

Is it normal to think of a crush that I met 10 years ago?

So I met this guy when I had an internship in Germany 10 years ago. He was my supervisor... We had feelings for each other but we've always been keeping a good distance... After I left Germany, I emailed him a few times a year to let him know what's going on in my life. Until last year, I've decided not to email him anymore... But recently, I've been thinking about him a lot, everyday... Whatever I do, I just think of him and wanna talk to him again..."""
