my head feels empty - anyone else feel this way?

I've been on these medicines:

Abilify 20mg - since 2004
Lithium 600mg x 2 - since 1999
Cymbalta - 30mg - since 2 weeks ago
Klonopin - 0.5mg x 3 - since 2004
Trazodone - 100mg - since about a year

Before I was put on Cymbalta, I thought I was pretty stable until I started having confusion and disorientation, obsessive worries and torments about certain things in my life, and generally a depressed outlook. So the doctor put me on Cymbalta.

2 weeks later I feel ok partway thru the day after taking Cymbalta in the morning, but now at about 5-6pm until I take my night meds, I feel empty in my head (only way I can describe it), and a headache. My spirits are ok, but I'm concerned about what's going on (or not going on) in my brain.

I feel like a complete test pig for the doctors. I know they're doing the best they can, but this is horrible. And getting off Cymbalta would be even more horrible. Any suggestions on what I could tell my doctor, besides what I've written here above?

my head feels empty most of the time lately. i take 20mg of Abilify and 10mg of Citalopram. about a couple months ago i was feeling great. i was productive. fully of energy. full of life. now i think i'm relapsing and starting to feel like crap again. lethargic, lack of interest in stuff, unable to relate to people again, and oh the paranoia is coming back.

. . .

anyway sorry for the rambling. point is i just feel like my mind is completely blank right now. i'm getting lost in my own little world again. however, i don't think it's related to a particular drug, but rather that my meds aren't working again.

hi,
can any one sujested that i am feeling lack of ambition in most of the time.1 year ago i am in job .i feel depreesion,disapointment,lack of confidence.can this type of felling lead to lose of ambition.in my college days i am very good student ,i am good in study.after cuming to out i felt so much trouble to search a job this create me lot of stress.but after getting job also i behave like same.everybody including my friends left me as saying that i am a mentaly disturbed persion.
