Not really all that similar to my symptoms. Except when I was on meds. Too many meds will put me there. Depression for me wasn't not feeling, it was wishing I didn't. Being on meds for depression and anxiety put me into this long state where I didn't really feel all that much, positive or negative. I was pretty joyless and difficult to be around, very difficult to love. But I was at least marginally more functional than I'd been before.
From my observations, though, depression can manifest in a lot of different ways at different times even in one individual. The spectrum gets spread all to hell and back once you start trying to encompass the general population. So, it shouldn't be that surprising that my symptoms were different. I'm also a lot further along the anxiety axis than it sounds like she was.
