Rie, I'm very sorry to hear this, and while you won't be able to play smash with us, you at least have us to talk with. I believe at this point from now on, I think it's time that you need to set your priorities straight and show your mother that you
can and will be a responsible adult. Life can be no doubt hard on most people, but as long as you have the will to get back up and better yourself, then that shows how mature you are. Don't let your mother drag you down because she has to set restrictions on you, cause while I do disagree with your mother's opinions on video games being a bad influence, parents are in a way supposed to help you get your act together. At this point you should set your priorities on meeting with your mom's standards and prove to her that you
can be a responsible adult, and
earn your right to do what you want. Focus on learning how to overcome that social anxiety and acting natural on a job field, and put all your efforts into writing top-notch resumes and filling out as much job listings as possible. Yes, it does take a bit of random luck to get hired in some way, but, as I said before, you never give up and try again and again.
