My literal best friend move to a different state and she had lived there previously and is pretty popular. We were the bestest of friends you could ever imagine and we still always talk to each other. But I can’t help to feel upset because she’s is constantly posting stuff with her friends and I feel like she’s replacing me. I know that she’s irreplaceable but I don’t know if I am a good enough friend to be irreplaceable. How do I stop being upset but keep the same relationship we had before?
