Scary Symptoms and No Answers

I am a 28 yr old female.  Starting two weeks ago I started having episodes of numbness on my left side, ear ringing, headache, blurry vision, and weakness.  It continued to get a little worse.  A week ago I started having a lot of mental confusion.  I have 3 children and I normally juggle 15 things at once but right now I am struggling to walk and talk.  Last Monday I suddenly was unable to speak.  I knew in my head what I wanted to say but couldn't get the words to come out.  I was admitted to the hospital for testing.  They have done a MRI, MRA, CT Scan, EEG, EKG, and have done a million blood tests.  We are still wainting for the results of one blood tests (antiphospholipid syndrome-which runs in my family).  All of my test have come back normal.  My speech has gotten better but I have to think hard to speak so it is slow.  The fatigue has gotten worse and it is going on 2 weeks with the headache and weakness.  The neuro in the hospital said its stress and sent me home on a antidepressant but my husband and I are not happy with this diagnosis.  Can someone please help me?  It is going to be July 30 before I see another neuro for a second opinion but I can't continue this way for 2 more months!
