Hi! A Few Days Ago I Ran Low Grade Fever

Hi! A few days ago I ran low grade fever for about 24-36 hours. My only symptoms were fever, chills, and sweating. Since then, I've had excessive thirst and fatigue. I'm drinking a lot of water and urinating very regularly (every 2 hours). I also have a blister like sore on my chin and an enlarged lymph node in my neck. Overall, I am tired and fatigued; just don't feel well. I have a history of Type II Diabetes and today my non-fasting blood sugar was 89. Other information: I've had a lot of stress as I've been unemployed for about 6 weeks. I am having extreme insomnia for about 3 weeks. I don't know how if any of that is relevant.
