Hello practo user I can understand the difficult situation that you and your family must be going through. It seems that your father is undergoing some stress either personal or professional which he is unable to share with anyone and that might be causing these distressing symptoms. As a family you can try and motivate him to spend some quality time and engage with him in his past enjoyable activities or hobbies . Try and talk to him regarding his work stress. You can also practice yoga with him as it can help clear the thoughts . It is advisable that you seek help from a clinical psychologist for a proper diagnosis and understanding of his symptoms . You can also reach out to me through the practo app for any further help or guidance.

I fear, he is under some pressure or issue... It is better to consult a psychologist...
