I lied to my best friend who is like a sister HELP!?

you need to explain to her that you were just trying to make her feel better and that you didn't think it would hurt her feelings. You also need to tell her how important your friendship is with her and that you don't want to lose her. You only have a brief amont of time left together so you should really make the best of it. The best approach is to talk to her in person and explain this because it is much easier to fight over text then it is in person. In person she will be able to see how upset you are about this. like i said before you need to be really really honest about this and let her know that she CAN trust you again. I hope i helped :) also can you please go answer my questions cause i need help with my own best friend situations lol
