Please read this part, thank you. 

I've suffered with anxiety for as long as I can remember, when it is really bad I feel almost possessed by this entity, I become numb, I can't move, I can't talk, I get angry. I end up hurting myself, I lose focus, cannot hear what people are saying even though I am looking right at them, I lose my memory and often forget what I am doing or was about to do.

Last night I got angry and smashed my whole room up which prompted my me to think wtf since I am usually a very calm and very quiet person. I have been completely debilitated by anxiety these past few weeks and I had been sitting on the floor for two days during the weekend unable to do anything at all but think about killing myself. 

Is this anxiety? Or something else I'm really worrying about it.
