Another Dr. visit

Just  what one needs - another Dr. visit for refill of med and another complaint. The nerve in hip. The inability to stand up for any length of time. The depression to accompany pain. What to do?  Dr recommends specialist analysis and recommendations. I recommend Lexapro again. My mind and body have crumpled into senescence and I hate both of them. Overactive mind and overweight body do not make a happy couple. Why must life go on?  FOR GOD'S SAKE.
