Feeling nausea daily morning. Something.

Hi, Since last 4 months i have been daily feeling nausea in morning. This started 15 days after when we started working from home. In the morning i feel like not eating anything and little headache. I don't get fear from thoughts but i keep thinking something or the other inside my mind. I feel bit feverish as well all the time. I have done CBC endoscopy LFT KFT and urine tests and all were normal except fatty liver. Vitamin D was less too. I sleep for 5 hours daily and when i wake up i cant sleep property again since something is running in my thoughts. I took Nexito forte but it caused vomiting to me and i stopped same day. I feel a bit feverish as well as sometime feel lack of strength in my hand and legs. Not sure if this is anxiety or something.
