New to anxiety and scared

Hi,

I am suffering with incredibly bad anxiety where I feel like I am going to lose my job, my girlfriend, and get a terminal disease.

I was late by 2 hours for my work, and am often running 5-15 minutes late due to poor planning. I’m scared that they will fire me, it’s a good job in a very reputable company that is sponsoring me to move to the US and I’m scared they will cancel this. 

Also my girlfriend is amazing, she’s here for me, tells me to go to therapy and we’re moving to the US together she’s American. I’m in London, she’s in Glasgow and have been doing long distance for a year. 

Recently I freaked out and had an anxiety attack, or believe it to have been. I was sobbing uncontrollably and a million things were going through my mind and all piling on top of each other. All the worst case scenarios. 

I have booked for therapy this Wednesday but am scared of how long it will take to open up, if I’ll be understood, if I can change.

I wanted to ask how do I deal with things right now? I keep getting waves of fear and can’t relax and keep fidgeting. Sleep feels like a way, but I don’t want to sleep. Sorry for the long post
