I am getting REALLY tired of getting sick no matter what I eat

carbs? bloated and sick. fat? headaches and nausea. just protein? keto flu

lately it's been feeling like my body is just giving up at digesting

now every time I eat I just get exhausted afterwards

like can't keep my eyes open exhausted

the only time I feel good is when there's no food in my body but that's obviously not a long term option
