Are rants allowed?

I was working on a tarot card design for 5+ hours, I had several layers of work and everything and my stupid ass, didn't check what I was saving as so I saved it as .jpg. I'm tired, mad, sad and I feel like crying right now. At least 2 hours of work is gone because they weren't visible layers, the canvas is 5 times the original size and my palette is gone. I can fix it for sure but I just wanted to share in case you have done something similar, just so you know you are not alone. Thank you.
