I was ok this morning, ate my breakfast, put the xmas decoration up etc, and then I suddenly felt really bad. I first thought it was because I had been standing up for a long time so I laid down but I'm not feeling better. I might say I feel worse. I have really bad n* , I feel yucky can't even smell or see food. I'm home,don't have to go out but I stil feel really anxious.

I know that no one can guarantee I'm not sick but do you think I could actually have a SV* ? I usually feel weird for hours before when that's the case.
It came all of a sudden few minutes ago...

If you have any advice please tell me, I'm really scared right know.
