No offense, it's okay if you find this dumb. But it's a little concerning to me since philosophy is a field of thought. And thoughts can differ. How can There be such a thing such as wrong or right philosophy.

If the only right philosophy is the philosophy that is made by previous philosophers, then philosophy has become a rigid field. And hence it would mean it's already done and there's nothing new.

I just find it disappointing that philosophy is now just sticking to conventional philosophy and philosophy that was made in the past as rules. Maybe to you my thoughts don't make sense, sure I might be wrong on the Existentialism, Nihilism and Absurdism part. That doesn't mean I am wrong when I created some of my own writings at the start.
