just thought i would add my 2 cents worth to the discussion.more than 30 years ago i was treated in an in-pt unit for depression after a failed suicde attempt.at this stage i was working as an enrolled nurse (= to your lvn) in a general setting.for quite sometime i wasn't allowed unescorted time of the unit,but nearly everyday a med student came and took me for a walk in tne park next door. it was her humane and caring treatment of me that a sparked an interest in mental health work. some many years later i went back to school and got my diploma of nursing & since (1994) i have only worked in a variety of mental health settings. about 6 years ago i fell back into that big black hole called depression, which required admission to hosp (to another facility,not where i was working) unfortunately all though trailed on a number of anti-depressants,nothing appeared to be working,so after much discussion i underwent a good number of ect treatments which just enabled to put my self back together,with alot of support from a community mental health team. i am still working in mental health. sorry this story is probably alot too long! but in answer to your query, sometimes i think just like in any other branch of nursing,sometimes it can help to have had some 1st hand experience. but i have always said that to work in this field you won't drive you mad,it just feels like that sometime!! sorry if this is too long winded
