Please think about getting some medical attention. Try calling your Doctors office and see if someone there can refer you to a reduced fee clinic. Sometimes the fees are based on your income. If they do not know of any, try a Google search. Please post and keep in touch.I hope you do not live alone while you are going through this.
I am so sorry you're feeling so badly. I would call your doctor now and discuss it. I think I have heard that some drug companies provide medications free for patients who cannot afford them. I would check into that.
Good luck and I hope you feel better real soon. Please keep us posted.
