In a word, no! At least not in any conventional sense. A mental illness cannot be spread the way a cold or viral infection might be but there are other dangers. Especially if you are close to someone who is dealing with a serious episode of depression, stress, anxiety or other mental illness.
There is a growing body of research to support the fact that living with someone who is clinically depressed, for example, may erode the mental and emotional strength of the very people who are trying to help them. Spouses, partners, children or parents can all find themselves worn down by the relentless demands placed on them by loved ones dealing with these types of illness.
This, in turn, can lead to feelings of resentment, guilt, frustration and others on the part of people whose only motivation is to help those people they care about who are coping with a serious mental illness. Eventually these states of mind may even trigger an episode of something like depression in the person who took on the role of caregiver in the first place.
Why is this important to know? It's quite simple really. Something we see all the time is a surprising lack of concern for people who are caring for someone with an illness. And this is not limited to mental illnesses alone. Everyone's attention, including that of the caregiver or caregivers themselves, is focused on the person suffering the illness. Little attention is given to the caregiver. Surprisingly, this is even true of caregivers themselves.
If someone who has assumed the role of a caregiver is sacrificing their own health and wellbeing in order to care for someone else, ultimately they will not be of any help to themselves or anyone else. As a caregiver you MUST know when enough is enough. Only you can know this. You do not need to feel guilty that you are not doing enough. You don't have to worry what other people are going to think. As a caregiver you have a responsibility to take care of yourself so you can take proper care of others. Professional caregivers like doctors and nurses know this all too well.
If you are caring for someone who is suffering from a mental illness we may be able to help. Cognimmune provides programs that aid in the prevention of mental illnesses such as depression and others. They can also be used to treat people already suffering from these illnesses. If you were caring for someone with a illness that you could be immunized against so that you would not succumb to the illness and be able to continue caring for your loved one you would choose to be inoculated, wouldn't you? Cognimmune offers you the possibility of doing the same thing in the realm of mental health.
Remember, there are resources available to help you and your loved ones. You do not have to go through this alone. All you need to do is ask for help as a first step. Also you will find some helpful insights at this link:
