With “your mind” undefined, solipsism is meaningless.
If only “your mind” exists and nothing else, then “your mind” (whatever it is) is the universe. How this differs from any other kind of universe, part of which can arbitrarily be labelled “you” and another part “me” escapes me. But feel free to disregard my opinion if you think I don’t really exist :)
