A doctor told me that it only means like “feeling no emotions” but other folks have told me that it means having a constant void that you have to fill up by being obsessed with something (like your FP or a fandom or a topic etc), addictions, being a workaholic etc because without those obsessions you would feel empty and meaningless and wouldn’t know who you were. 

Curious as to how folks here experience this symptom and what it means to them!
