"Mental state" is a bit ambigous. I think the traditional line
of thinking goes like this: The thought "Mary loves John." involves 
the same concepts as "John loves Mary.", namely the concepts "John", 
"loves" and "Mary". Nevertheless the two thoughts are quite distinct. 
So let's assume I agree that you are a mental state or a collection 
of them. You would then be constituted by a thought or a collection 
of thoughts. This means, if you hade very different thoughts, you 
would be a different person. Hence you are not defined by the 
concepts you entertain, since there are many very different ways in 
which these concepts could be put together into thoughts; and 
different thoughts would constitute a different person. So rather 
than saying that you are a collection of concepts, you have to say 
that you are a collection of conceps cum a structure defined on that 
collection. And I don't think it makes literal sense to say that this 
collection cum structure is an adjective -- it would be more correct 
to say that it was a proposition.
At this point I may also ask you if you don't think that feelings and 
values and desires enters in what constitutes being you?
Moreover, in order to be a human being, it is not enough to be a 
person. One also has to belong to the human species, and whether one 
does so presumably depends on one's ancestry and one's biological 
constitution, not just on one's thoughts or concepts.

Yes, on some deeper level I think I agree with you there.
