Dual-diagnosis care
Depression and Substance Abuse Treatment
Depression and substance use feed each other. Treatment that addresses both at once gives the best chance at lasting recovery.

About this condition
Depression and substance use
Depression is characterized by persistent feelings of sadness, hopelessness, and a loss of interest in once-enjoyable activities. It also shows up physically — changes in appetite, sleep, and energy. Combined with substance abuse, the two conditions exacerbate each other and make recovery harder.
Drugs or alcohol can feel like a quick fix for how depression feels, and that self-medication can develop into a substance use disorder of its own. Chronic use also changes brain chemistry, which raises the risk of depression. Our dual-diagnosis program addresses both conditions at the same time rather than one after the other.
Depression and substance abuse treatment runs at Ambrosia’s Singer Island program, with medical detox available in West Palm Beach. Levels of care span residential treatment and outpatient programs shaped around each person’s symptoms.
Symptoms of depression
Depression is not simply feeling sad or down. It is a serious medical condition whose symptoms interfere with daily life — getting out of bed, working, socializing. Severity varies: some people have mild symptoms that come and go, while others live with persistent depression that affects everything they do.
Thoughts of death or suicide are part of this symptom list. If they are present, call or text the 988 Suicide & Crisis Lifeline right away — it is free and available 24/7.

Types of depression
Major depressive disorder
Symptoms interfere with daily functioning for at least two weeks. Episodes can be severe enough to require hospitalization or intensive treatment.
Persistent depressive disorder
Also called dysthymia — a chronic form lasting at least two years. Symptoms may be milder than MDD but wear on a person’s life over time.
Perinatal depression
Depression during pregnancy or within the first year after birth. Left untreated, it affects both parent and child.
Seasonal affective disorder
Depression that arrives in the winter months when there is less sunlight. Treatment may involve light therapy and medication.
Psychotic depression
Depression accompanied by hallucinations or delusions. It requires specialized treatment.
Risk factors for depression
Several factors contribute to depression — genetic, biological, environmental, and psychological. Regardless of these, anyone can develop it: depression affects people of every age, gender, race, and background. Diagnoses are more common in women, while men are less likely to talk about how they feel, which leaves more depression undiagnosed and untreated.
- Family history of depression or other mental health disorders
- Traumatic life events — abuse, loss of a loved one, chronic stress
- Chronic medical conditions or illnesses
- Substance abuse or addiction
- Certain medications
How depression and addiction feed each other
Depression and addiction form a cycle that is difficult to break alone. People with depression may drink or use drugs to blunt their symptoms, which can develop into a substance use disorder. Chronic drug or alcohol use, in turn, changes brain chemistry and increases the risk of depression.
The overlap is common. In the national survey data cited by the U.S. Department of Health and Human Services, nearly 1 in 3 adults had either a substance use disorder or a mental illness in the past year — which is why treatment plans here assume the two may travel together.
How treatment works
Treating depression alongside a substance use disorder takes an integrated plan: both conditions are addressed simultaneously, by one team.
- Therapy
Behavioral and cognitive therapies — individual, group, and experiential work — address the thought patterns beneath both conditions and build practical life skills.
Medication management
Antidepressant options span several classes, including SSRIs and SNRIs. A psychiatrist who knows the addiction history chooses and monitors medication, adjusting as needed.
Aftercare
Recovery is long-term. Alumni services continue support through group therapy, individual therapy, and activities that keep people connected after the primary episode of care.
