Thanks both. I had no idea the symptoms would 'cycle' like this. I'm sure 6 weeks seems like nothing to most people on here but the symptoms are pretty intense and constant.

I guess it's hard feeling so out of control of what is happening, plus dealing with work and what might happen in the future with my job gets to me.

I worry about doing anything to be honest. Don't know whether to try and push against my symptoms to build up some kind of tolerance if that's possible or whether to just rest when I'm not at work (I'm doing reduced hours). Really love reading but then I worry about whether I should be doing that! Aaaaarrrgggh!
