Breastfeeding and exhaustion?

I'm still EBF breastfeeding, my son will be 1 in less than two weeks. He's BLW fed and has 3x meals a day with some snacks here and there if needed.

I'm not pregnant, but feel like I am in the first trimester all over again because of how exhausted I am. I am getting good sleep, take my vitamins every morning, and eating a healthy diet.

Is my exhaustion caused from breastfeeding still? It's been going on for months now but just chalked it up to #momlife but recently it's a whole different level of fatigue, like so tired to feel physically sick.

I want to continue with breastfeeding but concerned my hormones are all messed up. My emotions are also up and down with my energy levels so that makes me think it has something to do with hormones or a deficiency.

Can any of you ladies relate or have advice? Thanks in advance ❤
