You can't be contingent on yourself because of the very definition of the word contingent, end of.
More childish foot-stamping.
The definition of a word is irrelevant. The universe does not appear to require anything else for its existence. You can
call that whatever the hell you like.
You've applied the word 'contingent' to the universe, because
you claim it's contingent on its parts, so what do
you think they are 'contingent' on that has to be something apart from the universe?
Reconciling the language
you've chosen to use, is not anybody's problem but
yours.
