Pretty anxious the day after going back to work

So yesterday I completed my first day at work in 6 weeks and it was quite a long 10hr shift! And today I am left feeling quite anxious and a bit of an odd feeling, plus I had a really bad nights sleep. Hopefully as the day goes on I feel better.

Worrying about work

As soon as I woke this morning I started to worry about work, I think I get anxious about it in case I have another vertigo attack there, I feel like there would be nobody to help me, even writing this I am starting to feel anxious. I could do with another couple of weeks off to try and get myself prepared for it instead of just ignoring the thoughts of work I should confront them, but that raises my anxiety levels so I try not to think about it.
