depression
"I had severe depression when we moved from a house I loved in the country to a smaller house I hated by the river in a little suburb that I'd always detested.  Celexa works.  Most definitely but it works too well.  After being on it for 11 years, I became emotionless.  I had no feelings either way.  It also helped me to put on 50  pounds.  At 61, I decided to stop it.  I weaned my self off by cutting the pills in half, then in quarters, then none.  The side effects are the worst of any medication I've ever experienced....dizziness, SEVERE depression, SEVERE happiness, experiences in my head that I can only describe as "zits" that were instantaneous moments of dizziness or a feeling of a bug "zipping" by your head, fatigue, jitters."
