My Condition Got Worse Gradually

This morning, my auction ended, and only one product sold. I contacted my customer and prepared the shipment.
Last night, I took cold medicine before going to bed. I felt better this morning. I thought I almost completely recovered. However, my condition got worse gradually from evening. I don't have any appetite, I have joint pain, and I feel exhausted throughout my body. After taking cold medicine, I'm going to bed earlier than usual tonight.
