For the past month or so, I have been having feelings of lightheadedness and dizziness, my hands and feet get extremely cold and are hard to warm up, some slight nausea and at times when I m hungry, I have to force myself to eat at first because my stomach becomes upset before I start to eat. I have been worried about this as of late and have been having some anxiety attacks as well. I have a 10 month old son who I still nurse. I m not sure what this could be or what I should do as I do not have health coverage at the time being.
