My mother had problem from last 25yrs back.It all started when she started feeling that she won't be able to handle all the responsibilities she had to fulfill as an elder daughter in law and she also feels under confident that she was not able to do job and she is not independent.she had days of depression and normal days wen she has completely normal feelings.During her days of depression she use to sleep during entire day though she's not unconscious n is well aware of her surroundings but she refuses to talk,doesn't eat properly,doesn't bath for days and she wakes up in the evening and then she feels guilty that she had wasted her entire day and she cries a lot n such routine continues for 10-15 days and sometimes even longer and than she has normal 20-30 days and then again days of depression.She is taking antidepressants for the last 25yrs.she had been taking lithium,lamotrigine.At present she is taking lamotrigine,gudmansia.Her psychiatrist recently advised electric shock
