Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, your father is having psychiatric disorder complicated by
migraine.
So better to
consult psychiatrist and get done clinical examination and
counselling sessions.
Try to identify stressor in his life and start working on it's solution.
He may need additional anxiolytic,
anti depressant and anti psychotic drugs.
Ask him to follow these lifestyle modifications for better symptomatic relief.
1. Avoid stress and tension, be relax and calm.
2. Avoid excessive sun exposure.
3. Drink plenty of fluids orally and keep your self hydrated. Avoid oily and spicy food.
4. Take sound sleep of 6-8 hours.
Don't worry, he will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
