Hi, I understand your concern and would explain that your symptoms could be related to meth withdrawal syndrome. For this reason, I recommend consulting with your attending physician for a physical exam and some tests:- - A resting ECG - A complete blood count for anemia - Blood electrolytes for any possible imbalances - Thyroid hormone levels for thyroid gland dysfunction. If these tests result normal, you should consider anxiety as the main cause of your complaints. In such case, consulting with a specialist of the field would be necessary. Hope I have answered your query. Let me know if I can assist you further.
