Panic turning into feelings of guilt and depression

[Pickingflowers]

Hi Everyone,
I am on session two now, and today I tried to put what I am learning into action.
My first goal was to go into Starbucks to check on the status of my job application. I started to panic before I even left the house so I breathed and tried to calm myself down. It seems that every time I do this I go from panic to depression and feelings of worthlessness within seconds. It is almost like the adrenaline is covering up that "black hole" feeling I get in my chest when I am depressed. So, when I calm myself down, that is what I am left with. ...I think it would be easier to get things done with panicky adrenaline than low energy and feelings that I am worthless. I don't really know what to do about this.
Also, as soon as I got rid of the panic, my mother and sister started fighting. Every time I hear someone yelling I just go into a complete distress!! I hide in my room and cry until it is over. I used the six steps again this time, but again, I was left with feeling depressed. But this time it was much much worse.
All of this happened within thirty minutes. And Now I am in my room and can’t seem to get myself to stop crying. I am on a roller coaster. Good grief. I am sure this must happen to other people. Does anyone know how to fix this?
Thanks for listening
