Hello All these symptoms may be due to these possibilities , these include: 1 Diabetes , diagnosis can be confirmed by fasting as well post prandial blood sugar level . Also get in HBA 1c test for confirmation . Because all symptoms are indicating towards diabetes and above all your father is also having type 1 diabetes , so you are also prone to this disease. 2 Tension or anxiety may be the another reason of such symptoms . 3 Sometimes hyper acidity causes nausea , tiredness , tension , and frequent urination. Take some antacid , but if symptoms are severe you may need drugs like proton pump inhibitors like pantaloc-d . In my opinion first of all consult a physician and get his opinion. Good luck.
