I would try something like
-model 'emotion*group+age+sex+handedness+site+comorbid(1|Subj)'
Do you want to compare the groups at the overall average age across the three groups? [

Is it a dot (.) or dash (-) in those three group labels?
-gltCode adhd.p-adhd.d 'group : 1*adhd.p -1*adhd.d' \
-gltCode adhd.p-adhd.na 'group : 1*adhd.p -1*adhd.na' \
-gltCode adhd.d-adhd.na 'group : 1*adhd.d -1*adhd.na' \
> How do I introduce the three emotion conditions into each of the three group differences? Would I end up with 9 total lines for this 3x3 setup?
Depending on how many comparisons you want to infer, you can do something like
-gltCode adhd.p-adhd.d 'group : 1*adhd.p -1*adhd.d emotion : 1*pos' \
-gltCode adhd.p-adhd.d 'group : 1*adhd.p emotion : 1*pos -1*neg' \
