I can't speak for your W but having been depressed to what was diagnosed as a clinical state along with having anxiety that eventually manifested to a clinical panic disorder I can offer you the following from my own experience...
Being depressed and filled with anxiety is a very scary place to be. I felt so disconnected from myself, my surroundings and the people in my life that even the smallest tasks (walking the dog, getting the mail, going to the market) became monumental to me.
I think deep down I knew something was so very, very wrong but as most depressed people do I began coping with these feelings in a *very* unhealthy way. If I wasn't "hiding" I was lashing out. During that time I thought I was doing a bang up job hiding it from everybody. I wasn't.
Being depressed, at least for me, was an odd combination of wanting to hide forever and/or run away as far as I could. But you can't run from yourself.
I became physically ill, lost so much weight I was under the 100 pound mark, my hair started falling out in clumps and I lived each day feeling like I was on the verge of having a heart attack.
While it is was my responsibility to take care of me when somebody is in that state it is very hard to (A) admit it and (B) do anything about it as every minute of every day becomes a struggle.
My mom called me one day and I was in such a state I could not even breathe and honestly I can't even remember what I said to her. An hour later she knocked on my door, told me she didn't care if I was angry with her for the rest of my life and she gave me two options. Option 1 was allow her to take me to my dr. at once or option 2 was we were going to the hospital. She was loving but firm and in a way I was relieved because I was exhausted from putting up a front. I think she expected resistance from me but she didn't get it. I was in such a state I needed somebody to help me out but was too afraid to ask.
My mom took me to my long time primary care dr. who worked like hell to get me an appt. with a psych she has a good working relationship with. This dr. has a 6 month waiting list. That very night he opened up his office for me and that was also the very night my life started changing.
I am not making excuses for your W. I simply wanted to illustrate to you what I went through as a person. Nobody can make an online diagnosis but we can share experiences and I thought perhaps hearing mine might be helpful.
I knew my mom, sister, stepfather, brother in law, friends, aunts/uncles and cousins were concerned about me but I had no idea how frightened they were for me.
When my dr. was calling the psych. she knew well I heard her say to him "this is a broken woman who needs immediate help". And I was broken and *I* did need help.
