This happening now 

English it's not my main language so spare me a bit 

Today one the morning my mom came to my room to talk meanwhile I was eating my breakfast and during the conversation I asked her if she had any plans today she said that doesn't have any any plans, this is when the fuck up starts: I said that I have my SO invited me to eat again in her house with her family, yesterday I went to her grandparents house to pass Christmas meanwhile my mom was in a party. This pretty much made my mom mad told me to fuck off right now and leave the house because that was my plan from the get go (it was around 10AM when this happens). 

She got out of my room and went to hers closes the door and locks it. I don't go to negotiate with her because I better wait for her to cool off. But she didn't every time she got out of the room she told me to go away. 

About an  hour ago I just did that went to my car and went to sleep for a while, and I didn't said anything to her I just went away. She called me where the fuck I went and why I didn't told her and she got mad, cried and hangs the phone. 

Now I'm here writing on the garage with my cellphone thinking on how I go up to the apartment and calm my mother in the shitttiest Christmas ever. I pretty much want to jump from the window right now.
<bot>: I told my mom I had a invitation to eat, she wanted to pass the day with me but decides to get mad and send me away with I did and everything is shittier now
