Unfortunately there seems to be a language barrier between you and us, so most of us aren't 100 percent sure what exactly is happening in this situation you described, but from what I can make out from your posts this doesn't seem like something to get too upset over unless your mom is constantly exploding on you.
If your mom is very angry often you should talk to her about it, or tell her to seek help controlling her anger.
