B, You're on one of the worst parts of the emotional roller coaster. Have you looked into anti-depression/anti-anxiety meds? They really helped me at this stage. When they are working well (you may have to try a couple to get it right), they will really help level out the height of these peaks and valleys - not enough to make you feel nothing, just enough to help you cope with them better. Consider talking to your doctor about it.
