Based on my own experience, I would put #5 Discovering Your Authentic Self - (personal identity) at the top of the list. After waking up, I remember thinking: Now that I don’t picture myself in “the New System" in the next 5-10 years, where will I be? What do I believe? What do I know? How do I know what I know? What am going to do with the rest of my life? What are my goals?
I'm not a clinical or personality psychologist, but I also think #6 Dealing With Isolation and Loneliness (shunning) is closely related to #5. You might be able combine these and frame it as an interior/exterior thing: who we are is often as much the people around us as who we are “inside." Losing everyone around you can certainly make you feel as though you’ve been stripped of your real/authentic self/identity
Besides #5 and #6, I think it’s really important to mention #4 too. I went to a psychologist who specializes in abuse/PTSD/dissociative disorders for about 18 months and it helped immeasurably. Probably good at least to mention the importance of a good counselor no matter what other points you decide to discuss.
Hope this helps!
