I reported my work friend for telling me she was gonna kill herself and now she hates me how do I fix this?

I've been friends with this girl for 3 years and are friendship has been kinda toxic for a while but today work she told me she planned on killing herself in April I tried talking to some other friends about it but no one cared so I told my best friend but she's also a manger so she had to report it..

Now all my friends hate me but I couldn't just not do anything. They interviewed her and two other friends and asked if they should call the police. Now she hates me but I'd felt as if I had no choice

I've just checked as well and in the UK it's against the law to knowingly let someone kill themselves

If I'm totally honest I know how this may sound terrible but given recent events today I believe she said this to get a boys attention
