Hey man, I feel for you and can tell you from what you said in your original post, I can relate. I've been through some of things you've mentioned. I have anxiety too, my mother also has had anxiety and still does, she's been on medication on it for many many years, I remember my first anxiety attack was brutal, my mother was the person who I went to and she calmed me down after the attack faded. I thought I was dying, I couldn't breathe, I kept telling myself that I had to breathe. It's horrible and I truly understand. Everybody has anxiety, every person on the planet will experience anxiety some time in their lives, it's nothing uncommon and DO NOT think you're the only one. I know you feel alone, but you're not, you are here for a reason - i believe every human being is here for a reason. You just need to grasp yourself, life wouldn't throw anything at you that you can't handle. My advice to you is to talk to someone, anybody, a friend... family, doctor, perhaps you need different medication to help you, but you will get through this.
You need to find something to keep your mind off well... your MIND. Anxiety is created in your own head, it's created by YOU. I'm not a professional or anything, I'm just passing some common knowledge about this very common disorder. (Though I'm sure you've down your own share of research). But you just need to relax your mind, breathe deeply and practice something called Diaphragmatic Breathing, it helps a LOT with anxiety. It's breathing through your stomach rather than your chest, which could be causing you to have something very similar to what you're describing (something called Shallow breathing). Check out this link. It should help you how to learn, it's a step by step process. Very easy and effective for anxiety.
Anyways, hope you have yourself a great day/evening/night, and keep your head up man, things will get better.
