Hello! Welcome on Chat Doctor ! Your symptoms could be related to a metabolic disorder (vitamin B12 or vitamin D deficiency, an electrolyte imbalance, thyroid gland dysfunction, etc.). Anxiety or Epilepsy seizures can not be excluded either. Coming to this point, I would recommend consulting with your GP for a physical exam and some tests
