What do you think when she said "Now I feel more like myself too. For months I was in a weird state of panic or sadness or just feeling like I didn't care about anything."? Is this her trying to convey that she is in a new place now and almost admitting knowing she was obviously having some deep issues at work that caused this all to begin with?
It's hard to know exactly what they are thinking, because a lot of them are in a lot of confusion and turmoil even though they may not show it on the outside. When people told me that back when I was going through this mess I kept thinking "no they don't know her like I do and I see her every day, she is the Rock of Gibraltar on this!" Maybe a year after BD she told me the whole experience just tore her up inside and she cried every day about it. I was astonished, she seemed so firm and sure I just couldn't believe she really was in turmoil just like I had been told here. This is hard for most people here to accept, but while they may have known their FORMER spouse better than us, once they BD they turn into someone else, a WAS, and WE know WAS's better than their own spouses do.
Anyway back to your point, yeah I think there's an element of "I was sick, but I'm well now" to her comment. Right now she's still sending off friendzone vibes, so her intent may have been along the lines of "since I'm better we should hang out and do stuff." Waywards have to hit bottom before they might have an awakening, and I don't think she has yet. A lot of them will declare themselves "fixed" when they are still on the fall to the bottom.
