Do you suffer w/ depression?

And if so, how do you deal with it? I am Bipolar but I seem to get more depressed then high. I do love the high days though =) I am taking Prozac 20mg daily and Amitriptilyne 10mg nightly but I need to speak w/ my doctor as 20mg would suit me better. The night time one is to help me relax and fall asleep. I also exercise most evenings for 40 mins or so. My diet is OK but I think the depression just runs in the family as my Mother and her family have depression -( How do you deal with yours???
