I don’t like to give advice here because I’m not a therapist but as a patient who has sent texts like this, here’s a script you can use. Keep it short. “ hi, please disregard the text I sent last night. I was feeling really anxious and i poured that anxious energy into a long message to you. That was wrong, and I’m sorry. I hope we can catch up soon.”
This is really helpful, thank you!! She ended up messaging back shortly after I posted but I will keep this in mind for next time and I really appreciate you taking the time to respond!
I also have a really hard time with sending messages to people & then wanting to delete them or try to back track once I'm no longer feeling that way or bc I feel embarrassed about feeling that way & seeking that reassurance/validation or just anxious ranting
