Hi I Have Been Suffering From Many Of The Symptoms

Hi I have been suffering from many of the symptoms of attention deficit (I'm male 65 yrs old) also have feelings of panic, anxiety, confusion, some disorientation occassionally, and a sense of not doing well, not feeling like myself. Decision making is difficult. Staying on track. Feeling positive about the future.
My dr prescribed a depression medication. Lexipro? And something to take for one time issues like a severe panic feeling. my research shows its used for bi-polar. Took it once, sure helped calm me during an early morning sense of panic. He suggests chemical imbalance
What do you think?
