HELP feeling sick randomly

I trust the people who read this blog to give me advice. Sometimes your the only people who give me advice. I know I probably ask for a lot of it sometimes, but this time I would really just like to be told what to do.

Since Sunday when I was sick all day I have been feeling sick a lot. Its not normal sick though, it comes and it goes and I have yet to find any real reason for it. Its also not like a sick feeling that I have had before. I have a stomach of steal normally but I have been getting so nauseous lately. For today for example: I woke up feeling really gross but I made myself a bagel but could barely look at it with out wanting to throw up. I was also sweaty and shaky and it was not that hot in my apartment. So I took the bagel with me and on the car ride my stomach calmed down a whole lot. I felt good actually started singing. Walked to class and sat down and then felt sick again. I tried to make myself eat a little of the bagel in class but couldent make myself. So after class I sat outside for almost an hour waiting for a friend to eat lunch with and at that point started to feel good again... are you getting the pattern? When lunch time actually arrived I felt fine until I started to eat and promptly had to stop.

Because of this I haven't really eaten a meal in more then 3 days... I mean little things here and there but nothing like I normally do. I also realized just how soar my body is yesterday when I was in juggling class (yeah lol) and just a simple shoulder role caused so much pain. I have never felt like that before.

I am just tired of feeling like this, but the Tums that I have been popping are NOT helping at all. Is this a stomach bug? or is this stress? I wanted to ask my mom about it but when we talked yesterday... well its just not the right moment thats for sure.

thank you sooooo much
