According to the symptoms you report, it seems that you might have experienced reactive postprandial hypoglycemia (blood sugar lowering due to high levels of insulin in the blood as a reaction to ingesting a hyperconcentrated carbohydrates drink). Hypoglycemia (lower blood sugar levels) is characterized with nervousness, sweating, intense hunger, trembling, weakness, palpitations and often having trouble thinking and speaking. They act as warning signs to urge you to eat. At this level, the brain can still access circulating blood glucose for fuel. The symptoms provide a person the opportunity to raise blood glucose levels before the brain is affected.

If a person does not or cannot respond by eating something to raise blood glucose, the levels of glucose continue to drop. Somewhere in the 50 mg/dl range, most patients progress to neuro-glyco-penic ranges (the brain is not getting enough glucose). At this point, symptoms progress to confusion, unawareness, drowsiness, behavioral changes, comma and so-called non-epileptic seizure (non-epi seizure).

All in all, you might have gone to a wrong specialist for this matter. It seems that a more appropriate one might have been an endocrinologist-diabetologist who would have treated the cause-glucose intolerance.

As for the antidepressants, if SSRI (selective serotonin reuptake inhibitors) do not help, maybe your neurologist/psychiatrist might want to change your medication to putting you on serotonin-norepinephrine reuptake inhibitor (SNRI), but this is strictly a specialist’s decision.

However, it might be wise to choose a family physician, to coordinate the work of all needed specialists and who should know your whole health status best.
