Black and White

Right or wrong.
Yes or no.
Is it as simple as that?

Had a panic attack at work today, have no idea where it came from, just all of a sudden I was struggling to take a deep breath, my chest was so sore, and I went hot and sweaty.

Tonight I feel so panicky and anxious. I have come home and need to do a few things around the house but feel like I can't cope with them; it is only tidying and sorting bits.
I think of not doing them it makes me feel even worse and can feel my heart beat faster but physically I can't make myself get up and do them.
It is a horrible feeling and I don't know what to do.
