what's going on ?

I don't know what is going on with me.. but for the past few days i'm so dizzy and nauseated, i can't walk.. forget about exercising. I feel my heart somehow beating faster.. but i don't know if my blood pressuer is to high.. usually when i'm not feeling ok it gets to low, like 90/50..
I feel like i have to stop and breath.. but i want to throw up all the time.. i haven't yet.... trying not to..

I don't think i'm pregnant, having my husband on the academy for training for past 2 1/2 months.. there was not " much action " .. if you know what i mean..

Only change i know i had last few weeks is getting laid off from work, so i no longer have my " regular schedule " and i'm so busy running arround doing things, that i actually forget to eat, and if i eat it is less than what i used to eat while working at office.
I come to believe that i have been eating more before, bc i was stuck in an office so it was boredom.. but now i hardly want to eat....

I know some of you will tell me that this is bc of not eating enough, but even the thought of food makes me sick right now.. i don't know what i could eat- and even when i eat i don't feel better.. i did feel like this yesterday, and had fruits.. etc.. but i didn't feel better

Could it be the wheather ? I mean here in PHX the temps are changing really drastically.. 3 days ago i was laying in the sun and got a sunburn, yesterday and today it's cold


I don't know but it's frustrating to feel like this ..

ps. i do have anemia- i'm taking my iron pills, magnesium.. potassium
