An indication of irrational thinking is to see the world in absolutes, in black and white and not a vast array of grays.You wouldn’t support those things unless you are scared of something. It’s ok to admit you are afraid
While there are a few causes for this mental state, again, given your age, anxiety and/or depression would be common among those suffering from elderly dementia.

Black and White Thinking
Black and white thinking is when someone thinks in extremes. Learn more about what it is, what causes it, and what you can do about it.

Black and white thinking doesn’t allow you to find the middle ground, which can be hard to sustain in life at those extremes. Becoming less rigid in our thinking lets us stop using “all or nothing” statements to depress ourselves without examining whether or not they’re true. Using this 'cognitive' technique helps you to spot what you are doing and challenge your false impressions.
While it’s normal to experience black and white thinking sometimes in life, it could be a sign of something more serious if it becomes persistent. All or nothing thinking is commonly associated with these conditions:
Narcissism. Narcissism is an exaggerated, excessive interest in oneself. Black and white thinking can be a symptom of this personality disorder. People who have it will often find it challenging to get help because they quickly dismiss doctors and therapists.
Anxiety and depression. When people have anxiety and depression, it’s common for them to think in absolutes. More extreme emotions can cause black and white thinking to become worse.
Borderline personality disorder. Borderline personality disorder is a mental illness that causes people to experience intense feelings of anger, anxiety, and depression. They often will have symptoms of poor impulse control and frequently display black and white thinking.
Obsessive-compulsive disorder. It’s common for people with obsessive-compulsive disorder to think in absolutes because it gives them a sense of control and comfort. This can lead to a lot of rigidity which makes it hard to change.
