Weekend cocaine use want to stop

I’m 28f and for the past 6 months or so I’ve got into the habit of taking cocaine mostly just at the weekends when I’m drinking alcohol before this it would only be every few months or so . Half a g or 1g I really want to stop this it always seems a good idea at the time but the next day I feel like shit and have instant regret and anxiety kicks in about what I’m doing to my health I don’t even care about the money it’s more a health concern more than anything . Question I wonder is if you stop taking cocaine can you still live a long life I’m worried About the damage that could already be done .
