Topic: Confused at the moment

So I took the test and it said High Traits. Not sure the exact wording of it. I don't really completely trust it because it is online so it isn't 100% accurate. I just want to know what exactly Alexithymia is, and maybe your own personal opinions on if I have it or not. Biggest reason that I'm wondering is because I can identify emotions. Well at least some of them. Very simple emotions I can identify and understand, such as anger, sadness, or joy. But if it's more complex then it's more confusing for me. Also if I am feeling multiple emotions I can't seem to make sense of it all. I know that I am feeling something along with sadness, or another emotion but I can't seem to figure out what it is. Is this 'normal' for people who experience Alexithymia. Another thing is is that I feel that I can understand other peoples emotions and that I can interpret those just fine if not well, but that doesn't fit into the Alexithymia definition that I have seen.
