Create a simplistic, stylish, and cool cartoony design for a mental health brand. Use a soothing color palette with pastel shades like mint green, soft peach, and light blue. Incorporate minimalistic, hand-drawn elements and characters that evoke a sense of calm and support. Include an uplifting and motivational message in clean, readable typography. The message should read: 'You are not alone.' Integrate subtle, whimsical symbols of mental wellness, such as smiling brains, gentle hearts, or serene waves. The overall aesthetic should be contemporary, inviting, and comforting, aimed at making people feel supported and understood."
