As the other person said, there could be many reasons for the way you feel. I felt similar to the way you described on and off over a year for several weeks at a time, and for me it turned out to be caused by on overgrowth of yeast in my digestive system from taking antibiotics.

It took many different doctors and many tests to figure out what was wrong, so don't give up if you don't get an answer right away. Also, because of the anxiety feeling, doctors might assume that it's psychological or that you're stressed about something, but if you know you're not, don't worry. Hormone disorders and microbial overgrowth can cause your body to produce adrenalin or other things and make you feel sick, anxious, or have feelings of panic for no apparent reason. Good luck.

Hi
Welcome to healthcare magic forum
Please mention age and any other physical symtoms you may have.

Sickness in the morning can be due to multiple reasons . Try taking some light food (like cereal ) as soon as you get up.
If one doesnt sleep well, sickness in the morning is seen. Please rule out pregnancy as well, also any hormonal disturbance (irregular menses).

Anxiety and fears indicate you are going through some kind of mental stress,or it could be a disorder of thyroid as well.

You will have to visit a physician to find why this is happening and start the required treatment. In case every test turns normal you may visit a psychiatrist as this could be an anxeity disorder too.

Meanwhile try relaxing, indulge in light activty of your preference, timely and balanced diet.

Takecare.
