I'm going to snap at my mom when she's going through a rough time
I hope your kidding, you shouldn't yell at her even if your angry at her.
Yes, she bought me a laptop instead of a car.
Being mad at your mom for buying you a laptop sounds like a pretty selfish reason to snap at her. It will make her feel unappreciated, and it's terrible to do that to your mother when she's already having a hard time. You should be appreciative of what she was able to give you, and start saving your money to buy your own car.
You sound like my mom. Nah, I'm going to talk to her.
Talking is not snapping, but you need to be careful with how you talk to her. She's already going through a hard time and you got a gift and just sound ungrateful.
