Anxiety

매 한 줄

"매 Anxiety는 future-oriented threat에 대한 anticipatory response이다 — fear의 specific object와 달리 diffuse하다". Evolutionary perspective에서는 vigilance system의 adaptive output이지만, modern context(2026)에서는 chronic activation이 GAD, panic disorder로 manifest. 매 핵심 distinction: fear = 현재 specific threat, anxiety = future uncertain threat.

매 핵심

매 Fear vs Anxiety

• Fear: specific, present, immediate — amygdala-driven flight/fight.
• Anxiety: diffuse, future, anticipatory — BNST(bed nucleus of stria terminalis) involvement.
• 매 neural circuitry가 다름 — anxiolytic interventions도 다름.

매 Components

• Cognitive: catastrophic thinking, worry, attention bias to threat.
• Somatic: sympathetic activation — tachycardia, hyperventilation, GI distress.
• Behavioral: avoidance, safety behaviors, reassurance seeking.
• Affective: dread, apprehension, restlessness.

매 응용

1. Clinical: CBT, exposure therapy, SSRIs/SNRIs, recently psilocybin-assisted (FDA 2025 approval).
2. Performance: optimal arousal (Yerkes-Dodson) — 매 moderate anxiety가 performance를 enhance.
3. Decision making: anxiety로 인한 risk-aversion bias 의 calibration.
4. ML: anxiety-like behavior in RL agents (uncertainty aversion penalty).

CBT thought record (digital tool)

GAD-7 scoring

GAD7_ITEMS = [
    "Feeling nervous, anxious, on edge",
    "Not being able to stop or control worrying",
    "Worrying too much about different things",
    "Trouble relaxing",
    "Being so restless it's hard to sit still",
    "Becoming easily annoyed or irritable",
    "Feeling afraid as if something awful might happen",

LLM-based reframing assistant

from anthropic import Anthropic

def reframe(thought: str) -> str:
    client = Anthropic()
    msg = client.messages.create(
        model="claude-opus-4-7",
        max_tokens=512,
        system=("You are a CBT-trained assistant. Identify cognitive distortion "
                "and offer a balanced reframe. Not a substitute for clinical care."),
        messages=[{"role": "user", "content": thought}],
    )
    return msg.content[0].text

매 결정 기준

상황	Approach
Acute panic	Box breathing + grounding (5-4-3-2-1)
Chronic worry	CBT thought records + worry postponement
Specific phobia	Graded exposure
GAD score ≥ 10	Refer to clinician
Performance anxiety	Reframe arousal as excitement

기본값: psychoeducation + behavioral activation — 매 most evidence-based first-line for subclinical anxiety.
