ok so my friends are really being rude, and I don't know how to solve it! 

One day my friends were all in group chat including me. But I was out on vacation with my family and left my phone in the hotel room so I wouldn't be rude and go on it. When I got back and checked my phone I had like 80 messages (Lol group chat XD) and my friends were still texting at the time. So I was reading all the texts before I started texting with them so I knew what was going on. In the middle of readding the texts they had decided to talk about me while I was gone. And the next texts said "She's annoying" and "She brags to much". I have to admit when I talk to them I usally say small sentences like "lol" or "woooow" and stuff. So I decided to be mature about it instead of starting a fight (Which I end up doing without trying) so I told them how I felt about them sending those things about me. And they completely blew up on me and started calling me names and told me that I was fat (Even though I skinner then all of them) and bullied me! I told my dad about the texts where they said I was annoying and all but, I hid the name calling and stuff. Now my friends are ignoring me and I can't talk to my Best Friend because she is on vacation right now and I don't want to ruin it for her. So I came to what feels like my second family! :D Can you guys help me???
