Coping with tough days or relapses requires empathy and non-judgment. Remind your loved one that setbacks are a natural part of recovery, and they don't define their progress. Encourage them to practice self-care strategies they find helpful. Offer a listening ear without pressure to talk. Remind them of their strengths and past successes. If needed, help them access their support network or professional help. Reiterate that you're there for them, no matter the challenges they face.
