It's crucial to prioritize your mental health and seek professional help to better understand what you're going through and receive appropriate support and guidance.
The feelings of disconnection from oneself, memory issues, difficulty thinking, and fear of going crazy are all signs that something may be affecting your mental and emotional state. There could be various reasons for these experiences, such as stress, anxiety, depression, or other psychological conditions.
I strongly encourage you to talk to a mental health professional, such as a psychologist or psychiatrist, about your concerns. They can provide a proper evaluation and diagnosis, as well as offer appropriate treatment options, such as therapy or medication if necessary.
In the meantime, consider reaching out to someone you trust and sharing your feelings. Talking to a supportive friend or family member can help alleviate some of the emotional burden.
Remember that seeking help is a sign of strength, and taking care of your mental health is essential for your overall well-being. You don't have to go through this alone, and there are resources available to support you through difficult times.
