Core concepts
What this means in everyday life
Start with the ideas that relate to your experience. You can bring questions to your clinician.
Episodes matter
Mania, hypomania, and depression have characteristic patterns, duration, severity, and functional effects that require diagnostic assessment.
Routines protect stability
Sleep timing, daily structure, medication routines, stress, and substances can influence vulnerability.
Skills still matter
DBT can help with distress, impulsive action, conflict, shame, and implementing relapse-prevention plans.
Medical escalation is essential
Possible mania, psychosis, severe depression, or acute risk requires prompt medical or emergency assessment.
Try a focused practice
Turn the idea into one observable action
Choose a small exercise that fits the current situation. Stop and seek clinical or emergency support when risk, dissociation, mania, psychosis, intoxication, or medical concerns make self-directed practice unsafe.
Know personal warnings
List observable changes in sleep, energy, speech, activity, spending, irritability, withdrawal, or judgement.
Define the escalation plan
Identify who will be contacted, at what threshold, and what information they need.
Protect the ordinary week
Choose a small number of routines that make instability easier to detect and respond to early.
