I would not consider any kind of detox unless you have learned a lot - there are some big risks. With your current symptoms, I would look at nutrient support - good, nutrient dense foods, and some supplements - a good B complex (ideally with folate, not folic acid, Thorne makes a good basic B complex), A, D, K2, C, sublingual B12, trace minerals, magnesium. Being sick runs down nutrients even more, so this is where I would start.
