Hi there ~
I understand your concerns. Feeling of warmness, nausea
, spotty vision, lethargy
may all symptoms of hormonal
imbalance. You should get testing for hematology, renal panel, liver panel, thyroid
panel to confirm or deny these issues. An ophthalmological examination may also be in place. I also think that you should hydrate yourself enough to avoid feeling dizzy and passing out. I believe you might also need a CT//MRI brain, however a visit with a neuropsychiatrist might be helpful.
I hope this helps. Take care and have a lovely day!
