Hay, nakakahirap talaga maghanap ng affordable psychiatrist sa area na yan! Hindi ako personally familiar sa Alabang-Muntinlupa area kasi kami dito sa [area], but a few of my mum friends actually recommend checking with Philippine Psychiatric Association's directory or asking your local barangay health center, sometimes may referrals sila to clinics na mas reasonable ang rates. You could also try calling UP-PGH Psychiatry Clinic or Makati Medical kung may satellite branches sila nearby, kase sometimes mas mura ang rates compared sa private specialists, or look into government health centers na may mental health services. Sending you strength, mental health ay importante talaga!
