It's important to note that having a sense of being connected to the universe or questioning the nature of consciousness doesn't necessarily mean you have a mental health disorder. Many people have philosophical or spiritual ponderings about their existence and the nature of reality.
However, when these thoughts become overwhelming or distressing, it's essential to seek professional help. If you're experiencing borderline schizophrenic symptoms or any other mental health concerns, talking to a licensed mental health professional can be extremely beneficial. They can help you understand your thoughts and feelings, provide support, and work with you to develop coping strategies or treatment plans if needed.
Regarding your question about others feeling similar to you, it's difficult to say definitively as everyone's experiences and thought processes are unique. Some people might have had similar philosophical musings, while others may not. But remember, sharing common experiences doesn't validate or invalidate your own feelings. It's essential to focus on understanding and addressing your own thoughts and emotions rather than comparing them to others'.
Remember, reaching out for professional help is a sign of strength, and it can provide valuable insights and support. Don't hesitate to talk to a mental health professional to discuss your feelings and concerns further. They can better assess your situation and provide appropriate guidance.
