Remember if your answer is yes. Over-thinking is extremely harmful to one's physical and mental health. There are many disadvantages of over-thinking, but these are just a few of them.

Disadvantages of mental illness
The life of a person suffering from overactive thinking is full of worries. He keeps worrying about his past, present and future.Excessive thinking disorder can lead to problems. It also has a very bad effect on the stomach and some people do not sleep and some people sleep too much.

Someone asked that. I have a mental illness so severe that I can't tell. I keep thinking all the time If someone talks to me, I keep thinking about it. If someone doesn't talk to me, I keep thinking about it.I keep thinking about the days to come. I keep thinking about the days gone by
The pressure is so great that I can't sleep unless I think about it at night Thoughts bring sometimes peace and sometimes discomfort.

What is the solution?

If the current situation is bad then the mind starts thinking to avoid it. Similarly, if you do not like yourself or the situation, you are lonely.
Instead of trying to escape from reality, they start dreaming that maybe something will get better on their own without doing anything. This happens when we keep collecting problems and do not solve them simultaneously. The human mind thinks something. This thinking has an effect on every aspect of the body. People do not feel fresh, they feel down. Your whol personalty your body language, getting up, sitting down, eating and drinking, all things are having an effect on your mind.

It is very easy to control thinking. But basically we never tried to keep our thoughts under control. Control Your Thoughts Learn to Consenstrate and Focus If we learn to concentrate and focus, our thoughts become our employees. They are our servants. We say go away then think he goes so basically our servants are blessings of God for our benefit. Memories are our thoughts and imagination is our thoughts Memories Our past imagination is a future. Think should always come to your liking. It comes to people's minds why it doesn't work according to our will. Our thinking is not under our control because we have not learned to constnstrate.

Exercise

One exercise to make this easier is to have the person you trust the most in your life, maybe a friend, a family member, and talk to any trusted friend about all the things that keep you thinking.

Take time to think every day Set a specific time which is called thinking time.At least one hour in the beginning, then if you want, you can reduce the thinking time to fifteen minutes.And then you will just think and do nothing. For example, you set aside an hour for thinking until five o'clock in the evening. Whenever you think about it during the day, send a message to yourself that I will think about it in the evening, so your mind will become accustomed to thinking at a particular time instead of thinking all the time.

In exactly the same way. Like your stomach starts to feel hungry at lunch or dinner at a certain time.......so don't think a lot and If you think then it could be positive :)
