Anxiety Treatment in Manchester, NH

At Serene Behavioral Healthcare, we help patients of all ages understand anxiety and manage it with real, evidence-based tools. Anxiety is one of the most common mental health concerns our team treats, and it is also one of the most treatable when a patient gets the right support.

Conditions We Treat Under the Anxiety Umbrella

How We Approach Anxiety Treatment

Every patient’s anxiety looks different, so treatment starts with a thorough evaluation, not a one-size-fits-all plan. Our approach typically includes:

Comprehensive Evaluation

We take the time to understand each patient's history, symptoms, and daily life. For younger patients, this includes input from parents and caregivers.

Individualized Treatment Planning

Depending on the severity and type of anxiety, treatment may include therapy, medication management, or both.

Medication Management When Appropriate

When medication is part of the plan, we monitor it closely and adjust as needed, in partnership with the patient and, for minors, the family.

Coordination With Your Care Team

We regularly collaborate with therapists, primary care providers, and, for younger patients, schools, to make sure care is consistent across every part of life.

Ongoing Follow-Up

Anxiety treatment is not a single appointment. We track progress over time and adjust the plan as needed.

Signs and Symptoms of Anxiety

Anxiety does not always look like worry on the surface. In my practice, I see it show up differently depending on age, which is part of why an accurate evaluation matters so much.

Symptoms in Children

In young children, I often see:

  • Frequent stomachaches or headaches with no medical cause
  • Clinginess or difficulty separating from a parent
  • Trouble sleeping or frequent nightmares
  • Meltdowns or irritability that seem out of proportion to the situation
Symptoms in Teenagers

In adolescents, signs include:

  • Avoiding school, social events, or specific classes
  • Excessive reassurance-seeking or perfectionism
  • Trouble concentrating or a drop in academic performance
  • Irritability, restlessness, or trouble falling asleep
  • Physical symptoms like a racing heart, nausea, or muscle tension during stressful situations
Symptoms for Adults

In adults, anxiety often presents as:

  • Persistent worry that is hard to control, even when things are going well
  • Difficulty concentrating or a sense of being constantly "on edge"
  • Sleep disruption, fatigue, or muscle tension
  • Avoidance of work tasks, social situations, or responsibilities
  • Physical symptoms such as a racing heart, shortness of breath, or GI discomfort, especially during panic episodes
