Now it's Panic

What's next?  Went to work today and had to come back home.  Broke out into a sweat, started breathing heavy and fast.  Got a little dizzy and very tired. The same thing that happened last Monday when I had to come back home.  Guess I'm getting panic attacks.  I need and want to go back to work.  Why is this happening?  I love my work and have fun for the most part.  Thought I'd gotten better when I went to work last Friday even though I could only work a half a day.  Thought I was on my way back to health.  The pain never goes away completely.  It came and went over the weekend.  There were times I didn't need a cane to walk around the house.  I'm tired of all this B.S.!
