Is it normal is have no energy everyday? Any advice on what can help me? Details in description

So I’m almost 30 years old. I’m average weight. I don’t have any health issues that I know of Besides my iron is a little low. I’m on medication for it. I feel so drained all the time even when I wake up. I have a two year old. I don’t get any breaks. I haven’t had anyone babysit for me for months. If someone does watch him it’s not for long. Which I understand and I’m not complaining. My husband can’t help a lot. He’s a wonderful daddy ,but he doesn’t watch our child much for me.He will watch him for a hour or so every month or so. I’ve been telling my husband that I don’t feel good and I can’t physically keep up with my child anymore. I still don’t get much help with him because my husband can’t help much because of his job schedule. I return feel more drained. Lol Is this normal to be so tired?
