What do u do when you have a best friend for 7 years and they stab u in the back, and talk about u to your other friends and they don't tell u till that person moves the 8th year?

I'm in a depressing stage aswell.. trust me i know how it feels.. (but i wasnt stabbed in the back by a friend is all.) But brush it off don't let it bother you. she's out of your life.. be thankful and be a better person than she was twards you. I hope this helps.
