Thema: Is there a link to SDAM?

Does anyone know if there is a link between Alexithymia and SDAM and aphantasia? I know for a fact I have the latter two, and even though the test suggests I have Alexithymia, I am not positive. SDAM prevents one from re-living emotional memories, but I also think I don't experience the same level of emotion as others. I can readily identify emotion IN others though, although I tend to not "get" why they're so upset, for example.
I also bounce back from negative experiences more quickly than most, which can be surprising to observers. I never put that expectation on my family or friends, thankfully, but some may have been surprised at how I grieve, for example.
Still trying to figure myself out!
