Saying "I love you" is a strange thing to me

Nagsasabi ba kayo ng I love yous sa family and friends niyo? It's unfamiliar and not comfortable for me pero 'yung bunso kong kapatid na malambing keeps saying it to me and my parents. Ganun 'yung iba kong friends. Sorry sa term pero nagki-cringe talaga ako.

As an adult, unti-unti kong na ri realize na isa lang talaga buhay natin and gusto ko rin naman magsabi ng mahal kita or mahal lo kayo. Siguro sa thinking pattern ko rin and how I grew up na malayo ang loob sa parents and hindi naririnig sa kanila 'yun everyday.

How do you start? Paano masanay mag-express ng love via words? And does anyone experience this mental block?
