This is to know whether depression can make someone forget all the good things that ever happened in a seven year long relationship and just focus on the negatives from the recent past. (She face many ignorance and criticism from her family for past 3years. But now everything changed, marriage fixed. All are happy now and her family said sorry to her for past dramas happened. But now she is totally negative and she don't want marry. She is regretting about the relationship. Only focusing the negatives and blaming evey one. She is not moving from the past.) Should she take any medication? or she need anything psychiatric treatment?
