First of all all I am happy that you noticed changes in your friend and sought professional opinion here. From the description, it's difficult to make a diagnosis. It might be too much of stress or depression. I recommend that your friend should consult a clinical psychologist.
Here are few tips that might be helpful:
Spending some time on hobbies and with people in close relationships, i.e., family and friends.
Doing some physical exercise, yoga, meditation, etc.
Ensuring proper diet and sleep.
Writing a gratitude journal
