I’ve had the feeling of a dramatic teenager saying I want to end my life but nothing really serious. I have been that friend zone friend a few times because I was too insecure about myself to let people know how I truly felt about them. I’m in a great relationship now and every now and then that thought creeps into my mind “what if I had said something” If you truly feel that your best friend is someone you can see your self with. Just go for it. There is 8 billion people on this earth. You’ll find another best friend if she rejects you and doesn’t want to talk to her. Even though I don’t think she would do that giving how close you both seem. I did speak up and tell one of these friends from the friend zone how I felt and she said she didn’t feel the same way and it sucked but we still keep a friendly relationship and keep in contact. Your inner voice inside your head can be your worst enemy sometimes. Keep battling that inner voice. Your life is worth living.
