By the same technical semantics parsing, it is either impossible or trivial for anything to "make you somebody you're not", depending on how you parse it.
If it means that you aren't the person that you are after taking it, then that's obviously contradictory. You are always the person you are.
If it means that you aren't the person you were before taking it, then the medication is not necessary for that. At any given moment, you are always a different person than you were in the previous moment.
And even if you (erroneously) reject the latter, you would still have to concede that you are not the same person, after "fixing" yourself through non-pharmacological means, as you were when you were depressed.
