My friend and some of girls ganged up on me and got me into trouble , I was walking home with her feeling a bit brassed off and said about what had happened. She totally denied it so I was so angry she came my house (like every night) and I was quiet and totally ignored her. I had a text from her later on "have I upset you" I ignored it . As I needed to cool down now I have text her loads and she won't answer . She knows I've had a shitty week my dad is in Germany my pets died. Should I apologise? Idk what to do??
