So...the depression seems to be getting worse,not better. [View all]

what do I do?
I stopped welbutrin because it made me have seizures again,and started effexor.we've gone up twice.I'm already on prozac(high dose).I feel like sitting and staring at the wall.is this common with severe depression?What has helped you all in the past?Even though I would never actually DO it,the fact that I even entertain suicidal thoughts bothers me.
Thaanks for being my "Safe place"
