All of my friends saw my mom naked and she really embarrassed me. Should I forgive her? Any advice?

Today all my friends from online were over and we were playing COD on Xbox and some guitar hero. Then my mom came out. My mom is about 54 years old and an alcoholic who is always drunk. My mom knew I was having people over, but she did it anyway. I will never forget what she did. My mom walked down the stairs, yelling random stuff at me and all my friends cussing and swearing and she was completely naked smoking a cigarette. All of my friends were laughing and I ran up to her and grabbed her by the shoulders to make her go back and get dressed. But no, she just kept yelling and screaming and she began slapping and hitting me and yelling, with my friends laughing in the background. Finally, I pushed her into the room and I ran downstairs and made my friends leave. I haven't heard from them since. I am too scared to check my email or phone because I am scared of what they will say. My mom really embarrassed me. I almost hate my mom.
