"Neurosis" is no longer a well-defined term in the relevant professional community these days, but to the extent it has a specific meaning beyond being a vague synonym for e.g. "worry", it's an unresolved mismatch between your mental behavior/personality and the expectations of society. There are two ways to resolve that - change your mental behavior/personality and change the expectations upon you - and there's nothing in the definition to prefer one over the other.
