Hi.. Typically excessive Stress and Overthinking can cause physical symptoms like headache, body ache, sleep issues, irritability, change in appetite, etc.
Fever is not very common but yes our mind is capable of creating physical symptoms as defence mechanisms, this process is called 'Conversion'.
In your case it is probably your physical condition (vaginal infection) is causing this fever. Please consult your doctor (Physician) for it.
For Stress and Overthinking, please consult a Psychologist. Do not Google physical or mental health problems as it will not help.
