I think I have been wormed.

Okay, I do believe I have worms. I have been feeling movement in my abdominal area and I actually thought I was pregnant. I took a pregnancy test and it was negative. I have been really tired for the last few months with some minor bouts of nausea. My period has totally stopped, my anal area has begun to itch at night, my diet has consisted of nothing but Sugar because of the intense cravings, I have been having severe mood changes, etc. I am pretty freaked out. I was actually diagnosed falsely with intestinal parasites a while back (long story) but I think it is for real now. I think that because I have been through this before the edge has been taken off but I am still really scared of the thought of seeing them in my poo. I am also afraid that they will crawl out of my eyes, ears, nose or mouth. I need to know what kind of worms that I may have this time though so that I can get rid of them. Does anyone have any suggestions on how to go about this without going to a doctor? HELP, PLEASE!!
