Awareness:
The first step to overcoming obsessive thoughts is to become aware of their presence. Start paying close attention to what is going on in your mind

Meditation and Relaxation:
Regular meditation and relaxation practices can help balance the mind. They teach you to let go of tension and focus on the current moment.

Activity and Physical Activity:
Physical activity is a great way to distract the mind. Do sports, running or yoga

Replacing Thoughts:
When you notice negative thoughts, try to change them to something positive.

Rational Thinking:
Ask yourself the question: "Is it really that important?". Rational thinking can help separate real concerns from imaginary ones.

Gradual Adoption:
Remember that coping with obsessive thoughts is a process. Gradual acceptance and self-improvement lead to positive results.

Always remember that your mind is your space, and you can influence what happens in it. Do you often have this problem? Have you treated her with a specialist?
