Not the person you replied to, but just listening and allowing the person to express themselves and feel heard goes a long way. Getting it all out to someone and not being bottled up inside your own head can be a huge relief, even if the problem itself remains the same.

The instinctual reaction is to want to offer fixes. However, whatever the hearer thought of in five seconds, the sufferer probably also already thought of, and spent days/months/years attempting to make it work and it just didn't, and now the listening session gets diverted into kind of an argument where the suffered has to justify they have already put in sufficient effort to the fix the listener is pushing that it's not worth continuing on that road.
