Is Sour Diesel a good strain for anxiety?

I was wondering if Sour Diesel is a good strain for anxiety? I’ve been struggling with anxiety lately and I heard that Sour Diesel is a powerful and energetic strain, but I’m not sure if it would help with my anxiety or make it worse.

What is a cultivar?

I often see the term ‘cultivar’ used in discussions about cannabis strains. What does it mean, and how does it differ from other terms like ‘strain’ or ‘variety’?
