if you have a best friend, go and thank them for being there! I just did it and I have to say -I feel wonderful! My best friend completes me, she makes things worthwile, she makes it easier when life gets hard, it's not that bad to get over someone when I talk about it with her. Words can't even describe nearly how much I love her and how thankful I am to have her in my world, for all of the wonderful times we spent together and will spend :)
Friendship is more important than everything else, so go and tell your best friend how much he/she means to you, because you never know what happens and how much time you have left♥
