Is this due to sickness or do I have some symptom of burn out?

I've been behaving like a 6 month old baby since getting sick. I cried when my mom stole my apple slices. I cried when a stranger ignored me at the doctor's office. I cried when somebody I did not like was speaking in public. I don't know if my brain is exhausted and recovering from burn out or what is going on.

Is this due to sickness or do I have some symptom of burn out?
