How do you deal with anxiety?

I have chronic anxiety, I’m on day 3 of short breathes, tightness in chest, shaking, can’t hold down water. My body shakes as if I’m cold and have the shivers. I am so tense my blood pressure has been high. (I have a machine at home) I’m sick of living like this. Medicine hasn’t helped, I’ve been trying for years. Just once i want to be able to sit down and eat food without forcing it down. Without feeling like I’m going to puke after. I’m tired of shaking like a chihuahua. My hands and feet sweat so bad I leave marks on the floor when I walk. I’m tired of living like this
