Dear Doctor ... My mother is always going to depression by unneccesarily thinking like something is going to happen to my family member and she under treatment 5 yrs back .. but from that time she is doing dull and not active in any activities.She will do her work( she is housewife) cooking etc..she is almost 45 yrs old and not educated also. but sometimes she suddenly becomes dull unnecessarily thinking ....is there any permanent treatment for this kind of people
