i understand you...

try to make a routine for taking your medication... it wont work properly unless you take it everyday...
i take mine first thing in the morning when i crawl/fall out of bed and grab a cup of coffee - cigarette...
some times its easier to remember to take them before you laydown to sleep...

personally antidepressant by itself has never helped me in anyway...
i've tried several and the only time my depression lifted a bit was when i was over medicated - but i was taking a bit too many pills then.. all prescribed of course

i think the seroquel helped more than any of them... and the klonopins...
but seroquel will make you sleep so you have to take it like right before you lay down to sleep...

being admited to hospital didnt help me any... because i was being treated for bipolar anyway and i dont have bipolar... they just gave me more meds and increased the doses... the only good thing the hospital did for me was keep me from cutting myself...

do you have a psychiatrist? therapist? or seeing just a general practitioner?
regular doctors wont be able to really zero in on your symptoms and treat the specifics... if you cann need to get a psychiatrist - that is best because it is for the longer term ... the hospital can be good for imediate crisis intervention... but it wont make all of your problems just go away you know...?

im sorry you are having a hard time... i think its time for you to either increase the zoloft (50mg isnt that much..) i was on 200mg zoloft...
and time for you to see a profesional that can zero in on your symptoms and treat them specifically... with stronger meds...

stay strong... and keep writing here if it helps you even just a little....
