Mystery Illness

So, as you can tell I have not been posting a lot lately. I went home to visit my family and came back home very ill. See, I have been collapsing a lot lately and getting really disoriented and not being able to speak. It happens first two weeks ago, I went to my friend's house and as me and her were discussing a church event, I collapsed, I was unresponsive and unable to talk for 30 minutes. Afterwards, I have been very disoriented, I almost sound drunk (And I dont drink). I was normal for about 5 days (with bouts of headaches and nausea feeling) (Oh and no i am not preggs), then I fainted at church and according to witness, I start gagging and my eyes roll in the back of my head. Through, a miracle from God, they prayed me awake. Then the next day, I felt nausea in the morning, but by noon, I felt good. My friend came over and we had a good time talking and then I began to slur my words and she asked me if I was okay and I said no. Then I collapsed again, gagging and this time I was disoriented for almost 1 hour. I was admitted to the hospital and they dont know what is going on. At first they thought I was having seizures but now they dont think that. I am at home now, but still fainting and getting sick. I am not diabetic, not anemic, so we are really puzzled at this point. Keep us in your prayers.....
