Living with it
Support groups and helplines
- NAMI (National Alliance on Mental Illness): Free support groups and a helpline (1-800-950-6264) for people and families.
- 988 Suicide & Crisis Lifeline: Call or text 988 any time for free, private support in a crisis.
Back to school, work, or sports
- Most people can keep working or going to school.
- Ask about changes that help, like extra breaks or a flexible schedule. Workers may be covered by the ADA. Students may get a 504 plan.
- The Family and Medical Leave Act (FMLA) may let you take unpaid time off for treatment without losing your job.
Pregnancy and breastfeeding
- If you're pregnant or planning to be, tell your prenatal provider about this condition.
- Many mental health medicines are used safely in pregnancy. Stopping suddenly can cause a relapse.
- Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
- Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
- Mood problems can start during or after pregnancy. Postpartum Support International: 1-800-944-4773.
- Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.
For caregivers
- Listen without judging, and let them know you care.
- Encourage treatment, but don't force it unless they're in danger.
- If they talk about suicide, call or text 988 with them.
- Take breaks and ask for help. Caregivers need care too.

Connection can be rebuilt.
