I'm not really a professional author pero ang way ko para mailabas ang emotions ng mga characters ko and maisulat ang right words na siyang nag dedescribe sa nararamdaman ng characters is by putting myself on the shoes of my characters.
Lagi kong sinasabi sa sarili ko "paano kung saakin nangyari to? anong mararamdaman ko?"
Parang ganito lang, if your character is in pain, you should also feel the pain. If your character is happy, you should also feel their happiness. In that way, you'll be able to form into a words their emotions.
”In able for you to give justice to the emotions of your character, you should put yourself in their shoes. You need to feel their pain and joy.”
