Are there any nihilist philosophers who says nihilism is true without a "but"? No excuses like "art makes life worth living" or "you can create your own meaning"

I am looking for philosophers who believe nihilism is cosmically true, and that in fact art or music or self-expression does NOT make life worth living. You should attempt to die, or if too afraid you should just wait until old age while attempting to let yourself into a catatonic stance. of complete life rejection.

Does a view like such exist? I was told I was incorrect in considering Mainlander a total nihilist, so I am looking for a replacement.
