Hello sir I really appreciate your concerns and acceptance of her problem, also helping her cope and handle the situation.
Yes dealing with the anxiety, restlessness, helplessness and negative thought(some time) is a difficult task. I understand at this period for some people triggerance could be there. However therapy along with the medication helps the person to cope and manage the situation in greater extent.
But without knowing the actual problem it could be difficult to say which therapy could help your wife. There are various therapies for emotional problems. I would suggest you to consult the psychologist and they will discuss with you in starting of two sessions.
As it is lock down please try to take online consultation. During this period she can work on various aspects like her reasons for emotional distress. Let her create her own pattern to apply skills in various activities.
Take care, stay positive.
