"Create a thumbnail for an educational YouTube video about mental health disorders. This image aims to offer healing and understanding to viewers. The design should be clean and composed with calm color tones, incorporating elements that instantly evoke mental well-being and healing. Possible suggestions include a serene background in gentle hues, with a central icon or illustration symbolizing peace of mind, such as a lotus flower, calm water surface, or hands gently embracing. It's crucial to convey the message through visuals alone, without any text. The size should be optimized for a YouTube thumbnail at 1280x720 pixels --niji 6
