I Am Feeling Light Headed, Not Feeling Right, Feeling Weak,

I am feeling light headed, not feeling right, feeling weak, need to eat, sweating a bit, and feeling shaky. I ate a lot and still not feeling great. took my blood presssure and 129/88. This happened every once in a while. it started around 4:15 pm after a light lunch of soup and roll at about 12 noon. any thoughts. I am going to take a low dose aspirin just as a precaution, though I have no chest pain. just don't feel right.
