Or put differently, does anxiety always indicate a lack of bitachon.
Some claim that bitachon does not (always) mitigate or eliminate anxiety (see the discussion here 1 and Rabbi Netanel Wiederblank here 2, for instance). Others claim that bitachon does just that based upon the simple understanding of pesukim, such as אבטח ולא אפחד and the beginning of chovos halevavos shaar habitachon. Which view is correct? And more importantly, please provide sources that address this (as directly as possible).
