Being really tired was dangerous for me, now I know it is a phase and I try to in my mind not focus on how tired I am, I try to focus on "recharging" I was so mad when I got sober because I was tired all the time, it turns out that alcohol hides all the physical aches and pains, along with the crushing mental pains. Keep on keeping on, I have more energy sometimes now, not great energy, but so much better decisions, quality of life, etc.
