Thanks for asking the question and sharing your experience.  and thanks Lisa for posting the link.  I intend to check it out.  When there was a discussion of the MS laughing and crying, I found out that quite often psychiatrists will misdiagnose this neurological symptom as manic depression or some other kind of psychiatric disorder. I was seeing a psychiatrist for awhile.  I stopped seeing her because she did not seem to want to learn anything about what I was learning about how MS often causes depression, anxiety, inappropriate laughter etc.  I also found that some anti depressants made my breathing problems worse (constant yawning and trying to catch my breath).  Some anti-depressants left me too exhausted to get off the floor.  I found the most effective drug was diazepam taken when I experienced panic attacks. I also was told by my occupational therapist that when your balance is off your brain will often make you sit down by causing you to feel a panicky feeling in your gut. This feeling is, according to my OT therapist, often accompanied by nausea.  I am trying to get my neurologist to recommend a new psychiatrist that is experienced treating people with MS.  No luck so far.
