Anxiety attack or something else?

Anonymous
So today I was suppose to go to a trial for a internship I applied for but when I went to sleep I suddenly woke up a couple hours later at around 2:30am, in a sweat, tight chest and stomach and basically feeling like I was going to throw up, I tried several techniques to calm myself down and get back to sleep, I even tried to count sheep but every time I just drifted into a relaxed state my brain just caused a panic again and my heart was racing, I knew there was nothing to be worried about but my body was like in panic mode. At around 4am I just gave up and burst into tears because I was so frustrated because I wanted to sleep, I basically layed in bed for the next few hours until my alarm went off at quarter to 7, I attempted to get dressed but felt extremely dizzy and weak that I had to lay back down. This has really never happened to me before and when I told my mum her response really upset me... She basically in her own way told me to get over it, when I was obviously distressed and panicking and I even said that I don't have control over it but she still treated me like it was my fault, it seemed like all she cares about is me getting a job and not really about my well being.

I still feel sick to this point, even though I have rung in and told them I am not coming.

What is this and what do I do?
