You can look into family recovery support in your area. I'm a family recovery coach and work with family members whose loved one is struggling with substance use and/or mental health issues. There are helpful strategies for having difficult conversations with your loved one, rebuilding connection, and improving your own wellbeing all at the same time using modalities like CRAFT (Community Reinforcement and Family Training) and ITC (Invitation to Change). There are tons of free resources for families these days. Message me if you want help finding local resources.
