Yes, I think it's normal......at least for us. When I was first abandoned, I fluctuated wildly from one emotion to another all day long, but most of them were negative. And my mind worked "black and white". When feeling sad, I was desperately, suicidally in some cases, sad; and when I was happy, I'd convince myself that the worst was over, but, of course, it would inevitably start all over again. Now, I'm still doing this but it's being measured in days instead of minutes. I'll be fine for three or four days and then something will happen and I'm back where I started. I still have the shorter episodes, but I think with the help of some of the DBT techniques and time, I've been able to cut them as well as their frequency and intensity down.
