Being a ghost for a while probably didn't help, but I was bitter in general before death, too.

I mean, sure. I've got more purpose now. I do things with myself, and I'm technically better for it. But it doesn't get rid of that feeling like I should lock myself away in some dark room for a week straight and refuse all human contact.

Which would be way easier if I was still a ghost since then I wouldn't have to worry about silly things like "eating" or "biological necessities".
