Why is that sad? Situational depression is the best of many bad options as it’s the case where a badly needed change can actually have outsized impact.
The general advice given is that everyone wants to change their circumstances when they're unhappy but supposedly our circumstances only account for 10% of our happiness with 50% being genetics and 40% behavior. So everyone tells you stop trying to change your circumstances and change your behavior instead. So, the OPs experience 'sadly' doesn't fit the formal recommendation.
