寂しい (sabishii) is an adjective for everyday loneliness or missing someone/something. 孤独 (kodoku) is a noun for a deeper, often existential solitude. Use 寂しい for 'I miss you' or 'I feel lonely tonight'; use 孤独 for 'the loneliness of modern life' or philosophical contexts.
While grammatically correct, saying あなたがいなくて寂しい (I'm lonely without you) can sound overly direct or dramatic in Japanese. Often, simply saying 寂しい with context is enough, or using the person's name instead of あなた.
