Negative thinking by itself is not a disease, although it is not healthy for you and can put you at risk for other diseases, even a shorter lifespan! However, it can definitely push you towards depression, or be a an early sign of depression, especially if it is not your normal way of thinking. One of the treatments for depression we have is teaching people positive thinking habits such as looking at a glass as half full rather than half empty, i.e., concentrate on what you have rather than on what you have lost. The disease of depression is a constellation of symptoms that include other things than negative thinking, such as changes in mood (sad feelings,) or ability to enjoy things (not able to have fun anymore or a tendency to socially isolate yourself,) or changes in sleeping or eating patterns, or self-esteem getting low, or thoughts that life isn't worth living, or not being about to concentrate, make decisions, or remember things. It is often accompanied by increased worrying, although not always. If other things are changing for the worse besides your negative thinking, it is probably worth a trip to your primary care provider to get checked out for depression.

However there could be other explanations. I would suggest you speak to your regular doctor who can do some screening and refer you to appropriate professionals (psychologist, psychiatrist or others) indicated.
Your doctor should also check for obvious medical causes such as thyroid disease, nutrition or even cancers according to your demographics or risk factors. Regardless of the etiology, there is a lot of wonderful positive mindedness research to show its benefits in all aspects of health, mental & physical, and in coping with daily life stressors. You can work on this on your own, not to discourage psychotherapy. NY Times magazine had a special edition on mental wellness this summer and a lovely review of resilience and how anybody can learn positive mindedness, regardless of personality or traumas. You could easily google up a plethora of articles on this. Nevertheless, you should still go and discuss this with your primary doctor.
I wish you well,

A major depressive episode or clinical depression is defined as a 2 week or more period of time in which a person's mood is sad with loss if interest or pleasure and several associated symptoms such as problems with appetite, sleep, excessive guilt, poor concentration, memory problems, feeling slowed down or restless, feelings of worthlessness, hopelessness, helplessness, low self esteem, low energy, low motivation, and even suicidal thoughts. These symptoms impair a person's functioning at home, at work, or in social situations. If you are experiencing some or all of these symptoms, please contact your doctor's office for an evaluation.

The longer answer would need to take into account what exactly do you mean by negative thinking. Often times, negative thoughts may emerge in response to certain situations or events, or even certain people, and many times, the explanation for those thoughts may not be apparent or obvious to someone who is having such thoughts. There may be other times when negative thinking can be an early harbinger of illness or a symptom of an illness already present. It typically takes a trained professional to know when such thoughts are related to situations and when they become symptoms of something else. The question to consider asking yourself would be: Do these negative thoughts in any way impact or interfere with your social, occupational, or work life? If the answer is "yes", you may want to consider getting a consultation with a trained professional who can evaluate your concerns and ask further questions which would then point you toward the correct answer, as well as offering recommendations to remedy, resolve, or manage these negative thoughts effectively. Best of luck in your quest.
