I have been feeling very odd for the last 3 weeks, but it's something that I've had on and off over the past two years as well. I am constantly feeling nauseous and my heart seems to go through periods of beating very fast or seeming like it's slowing down plus my head feels fuzzy a lot. I have not been sick, however.
I realised that the nausea seems to retreat as soon as I leave work, and starts again when I'm going to work in the morning. The chest issues are mostly at night when I'm trying to go to sleep but also at random points throughout the day.
I do have a Drs apt booked for next week, but have been wondering whether it's anxiety related, rather than something else. When I was at uni I was constantly stressed and anxious, but it would make me physically sick every day, which is not what is happening now.
We've moved offices at work and I got a new boss after a year of not having one, but in terms of being busy at work etc. it's generally not been that stressful recently - definitely not as stressful as it's been in the last 4 years. So I'm not really sure what to make of it all.
Sorry for the long post - it's helped to write it down.
