Yes, anxiety attacks can be subtle and may not always manifest in the same way for everyone. While some people experience intense physical symptoms like rapid heartbeat, shortness of breath, and sweating, others may have more subtle or internal symptoms like the ones you've described.
The experience you've described—where your thoughts become louder, feeling overwhelmed with overthinking, and experiencing a sense of time distortion—is consistent with what some individuals might experience during an anxiety attack. This can be due to the body's fight-or-flight response being triggered by perceived threats, even if the threats are not immediately apparent to others.
Anxiety attacks can be distressing, and it's essential to take care of your mental well-being. If you've been experiencing these episodes frequently or find them interfering with your daily life, it's a good idea to seek professional help. A mental health professional, such as a psychologist or psychiatrist, can assess your symptoms, provide a proper diagnosis, and offer guidance and support in managing anxiety.
Additionally, incorporating stress-reduction techniques into your daily routine, such as mindfulness practices, deep breathing exercises, regular physical activity, and maintaining a healthy lifestyle, can also help in managing anxiety symptoms. Remember that seeking help is a sign of strength and taking care of your mental health is vital for overall well-being.
