When I was young, I went through stressful moments and since then, my breathing pattern has changed. It's really hard to explain, how could you not know how to breathe? It's supposed to be so natural. I don't know why, but I just can't breathe. It's like breathing and holding your breath at the same time. When you are having a hard time even just to breathe properly, it's really hard for you to do anything else. I can't focus on work, I can't make friends. And I just can't stop comparing myself with other people, even though I know I shouldn't be doing that. It's like they have everything and I just have got nothing. How to get these negative thoughts out of my head?
