I Have Already Been Diagnosed With Anxiety A Few Years

I have already been diagnosed with anxiety a few years ago, but I feel like there's more. I get very upset and mad easily, especially when it comes to family. If I feel like they're getting an attitude with me, I blow up easily. I scream, yell, punch walls, and some times hit myself. I've been through things in the past with family, but I feel like i've gotten over it, but also feel like the more things that I go through with just life itself, people going in and out of my life, i feel like it gets worst. I stay confused alot on situations, i'm always tired, and my mind always feels slow. I'm a female, and i'm 22 years of age.
