I got angry with my mom suddenly

Assalamualaikum. My mom is the person that i am very close to. I was with her all the time and still am. My mom gets angry for many reasons. Sometimes because i did not do the work properly like dishes or me being late to go for ghusl and many more reasons. I promise you i never want to shout at my mom. But i cannot seem to hold my tounge. I hate myself for not able to hold my tounge and not talk with my mom rudely. Today i was delaying my time for a bath. My mom came and hit me. I got angry and told her " ill go when i want to" She again hit me. I told her to put down the ruler in a rude way. She got more angry. She doesnt want to talk to me now and i am trying make her laugh. She laughs but still she does'nt talk to me. I don't even know if i deserve forgivness. Whenever i get hit i act very rudely. I don't know why. But i really love my mom. So does my mom loves me. But we both share a similar thing that is our anger. My mom cannot control hers. But i should control mine. If i ask forgivness from Allah. Will he forgive me??
