Do people really don't see our pain unless we tell them?

All my life, I've hidden my pain from everyone. Why? I don't know. I could never express it, even as a child. I (22, F) was sexually abused as a child for years, and it has stolen away my life from me. I don't know what peace is. I live in constant fear and my heart is always heavy. I don't even know what I want in my life to feel better. I don't know if anything can make it better. Every day, I walk around masking my pain, putting on a smiling face when needed. I still suffer from nightmares but try my best to be “happy” in the morning so I don’t ruin my family's mood. I’ve failed at times, and they’ve complained about my pain affecting everyone. I’ll keep my story brief. Today, someone I see every day asked me, “What have you seen in life? What pain do you have? Do you just create pain in your own head to say that you've had a difficult life?" It stung deeply, but I couldn’t say anything. I can never say anything. I’ve heard the same question (in different forms) from my family - my mother, father, brother, sister, and grandparent. While I understand that I need to talk about my feelings for them to understand, I wonder why can’t they see the pain in my eyes? If you love someone, shouldn’t you be able to see their pain? Does it only happen in books and movies? Or have I become that good at hiding it? I know it’s probably unfair to expect others to know, but is my pain truly that invisible? I'm afraid that the coming year will be just like this one. There are lots of questions in my mind, but I’ll save them for another day. Happy New Year!
