you cannot compare yourself to what your sister said. everybody has their own measure for depression. i learned this a long time ago. i had a friend who was on disability for depression. disability...this to me meant that she could not function because her depression was so bad. so we were in art therapy and were talking about my suicidal tendencies. she says to me, "when you get that way, call me and we will go take a walk or something." and i was flabbergasted. seriously? go take a walk? has she never been suicidal? and she hadnt. so i learned then that depression is different for everyone. i function, have a job and wanted to die all the time. she couldnt function due to her depression, yet never thought about suicide. if you dont have a therapist, please seek out help. take care.
