I lost my best friend....

So my best friend has been dealing with anxiety and depression, and she messaged me saying “I’m going to be gone for awhile” and “ I’m done”. I messaged her saying what do you mean and nothing. I messaged her husband asking if she was okay. I didn’t know if he would of had his phone on him while he was at work or not and he can’t drive right now she is the only one able to drive. So I called the police to do a wellness check on her and she blew up on me saying “you called the cops”? “I’m perfectly fine” “you should’ve called Kevin”(her husband). I messaged him before I called the police and he didn’t answer by the way. Both of them made me feel really shitty and like I did the wrong thing. Well this is the newest messaged I got from her.

So question for you guys is, am I a horrible friend? Cause I surely feel that way. I know the last message was uncalled for but I was done being treated like such a horrible person for looking out for her.
