Join a co-working space, work from cafes (can be hard too) or rent an office with friends. Why? Keeping the work at work and enjoying the time at home will be a good strategy against burning out. Of course it will take you some time to commute or be more expensive than just staying at home, but it's a good way to stay sane. Maybe you can also create your own office in 1 room and be at home in the other rooms. But you might be tempted to work longer than what is healthy.
