update on Imipramine

Well it has been almost 3 months since I was prescribed Imipramine and it has brought me to a level that is above suicide but still have depression it is from my life that has been racked from the illness . 1)I still have ED and that depresses me and a erection in a pill is a real boost to your self esteem NOT...2)sleep is still shetchy and I am not getting REM sleep .I am up and down all night sleep for 2 hours and up for 2 hours it is really frustrating and being tired all the time sucks and depresses me ....3)I am dizzy allot and am afraid of things real fear where my legs shake and I am dizzy but I keep on trying to live a normal life (NORMAL) WTF.I just want to live a average life and have some type of real life. I am depressed so much and am waiting to see what my shrink says before I make any decisions about my future . I am concerned about my future I am having trouble fighting off the desire to die .
