I cant understand why I have the feeling I want to cry much of the time.  I do have stress with a husband with Alzheimers disease but I deal with it.  Sometimes not too well.   I get so frustrated with him.   Having said that, I dont feel the need to cry after an episode with him.  The crying feeling comes and goes at random.
Degree understand your concerns went through your problem description. You are really courageous and self-reliant, that you are looking after your husband who is suffering from Alzheimer s disease. Surely you will get its worth from the creator. Random crying feeling is associated with minute depression. Don't be alarmed. You are stressed, over and above distressed. Crying is quite normal for people who are distressed. Therefore, just ignore this. Concentrate on your daily routine, husbands welfare, your family welfare etc., god is with you always. Hope this answers your query. Available for further clarification. Good luck.
