It is possible that you are experiencing what is commonly known as "anxiety paradox." This is when you feel anxious or worried even when things in your life seem to be going well or when you are happy. It can be confusing and frustrating to feel this way, but it is not uncommon.
One possible explanation for this phenomenon is that you may have a tendency to focus on the negative aspects of your life, even when things are going well. This can cause you to worry about things that may never happen or to feel anxious about things that are out of your control.
Another possibility is that you may be experiencing some underlying stress or anxiety that is not immediately apparent. This could be related to a variety of factors, such as work, relationships, or personal issues.
It may be helpful to explore these feelings further and consider talking to a mental health professional. They can help you identify any underlying issues that may be contributing to your anxiety and develop coping strategies to manage these feelings.
