I hate to say it, but you need to ignore them and not pay any attention to their advice. I went through something similar with my parents. I had to tell them that I love them, but please don’t give me advice about things you know nothing about. Humoring them was taking a toll, and I don’t have energy for that anymore.

Get a day job for a while, reflect on lessons learned, and think about how you can scale back your idea or think of another idea that is scaled down enough that you can get it going in your spare time.
