You poor thing! I have read a couple of your posts. Some of your symptoms are typical of tick-born illnesses. I got bit by some ticks in the summer and now have Borreliosis (Lyme Disease). I too had easy bruising. In fact, my husband and I were playing around with each other and he smacked my leg with a plastic hanger. My leg bruised and it stayed for 4 weeks. If I bump into anything, I bruise. If someone taps me to hard, I bruise. It's so weird! I feel a lot of the symptoms you feel with mono. I sleep 12-14 hours a day and take several naps during the afternoon. My body aches something terrible! The sleeping is due to the exhaustion, because your immune system is so weak.
Have you ever heard of Wilson's Syndrome? Here are just a few of the many symptoms: fatigue, headaches, migraines, pms, irritability,fluid retention, anxiety, panic attacks, hair loss, depression, decreased memory & concentration, unhealthy nails, constipation, innapropriate weight gain, dry skin, dry hair, insomnia, falling asleep uncontrollably during the day, hives, acid indigestion, asthma, allergies...and there are a ton more. Wilson's Syndrome has something to do with low metabolism. I have had some of these symptoms with my Lyme disease. I do hope that you get better soon!
