Exactly this. For the sake of argument, let's assume you try 10 different strategies over the next 6 months and all of them fail to reduce the overload. Will you still feel responsibility for not being able to keep up? A lot of people don't recognize that sometimes you can't fix a situation and that isn't your fault. Burnout comes from that - lots of effort with no result. A great sign of this is that the company has hired more people and the workload increases to keep everybody overloaded. As ThrowawayR2 said, don't enable this behavior and take responsibility for working nights. Push back against requests and work a sane amount of hours. Make it clear to your management that the workload isn't sustainable. Do this so when you look back you don't ask yourself "Should I have been more clear with management? Was I the problem?" If that isn't supported then find another job.
