Cant find the answers

Symptoms Random anxiety, slowed metabolism, muscle loss, brain fog, trouble sleeping.

Bloodwork, sometimes testosterone low and cortisol high, but seems to be fluctuations. Otherwise all my bloodwork comes normal Had a brain MRI all came good.

Gastric emptying scan: delayed

Seems like certain carbs and gums/emuslfiers make me feel worse, even veggies do. This could all just be a chain reaction. Whole grains as well. If i eat foods that dont bother me it helps but doesnt get completey get rid of it. Probiotics help me feel better but not 100%. Past 5 years everyday felt like this. I only feel bloating and acid reflux regarding ibs. Any ideas???
