Relationship Help?!?!??😩😩

So I’m long distance dating this amazing girl that I’ve known forever. Recently when we both came out as bi I began to get feelings for her. After a couple months of keeping those feeling to myself I told her. She said she liked me too and we’ve been dating for only 5 days. Since we’ve been friends for years

and know each other so well we already said I love you to each other. The first 3 days were a crazy blur of I love you’d and pouring out heart out. But as of yesterday she didn’t text me much. She didn’t send a good morning selfie that we always do and she just seemed distant. Am I over reacting or is new relationship already doomed.
