Can't connect properly with my parents

I'm 14 now and I sort of feel like I don't have much of a connection to my parents. I can't share things with them, I can't talk to them without getting some sort of judgement.Today my mom was getting late for something and started telling me a link that I needed to search online so that we could repair an apparently faulty Ethernet switch. I started mistyping by accident because sometimes her instructions seemed unclear and she was getting understandably angrier since she was low on time. Out of nowhere, I sort of snapped too out of frustration and told her that she can type it. She took it really personally and said that my bad attitude is because of my overly "Westernized" beliefs and that when I grow up, I'm just going to abandon her and the family. Stuff like this has been happening since I was 9.​I don't want to talk to them, because I feel like it's just gonna circle back to me being 'lazy' or 'playing too many games', so I just keep them to myself, or at least tell my friends instead. I don't want to be stressed out any further about my comparatively bad grades (Mostly B's, only a few A's. Bad for Asians).​I can't ask for help without the lingering feeling that it is going to end with them ranting at me about bad grades and my rude Western ideologies. Everything I may accidentally slip out will be taken very seriously and I can't do anything.Is there any way to mend this somewhat broken trust, or at least talk to them? via /r/Parenting http://bit.ly/2weKRBq
