Long story short my party was last night my sister is my maid of honor and booked a hotel for all the girls. Well i got very upset at her because she left me to go with a friend of hers to a bar and did not come back all night. She came back to the hotel in the morning and i was so drunk i started screaming at her and we got in a huge fight. She then told me she does not want to be in my wedding anymore.I keep trying to call and text her but she is ignoring me. I really do not know what to do. My mom got involved and she is mad at me and i am feeling very depressed i feel so bad i compleatly blacked out and drank too much and apparently i ordered wine that i do not remember ordering from room service and they charged her for it i offered to give her the money for it but she just got upset. How can i difuse this situation?
