I figured out some years ago that I can't use Please, Sorry and Thank you for most things. Or if I do use them, I feel like I'm saying those in an ironic manner as if I don't really feel like saying them.

It could be because my parents don't use these words themselves. I've never really been thanked for helping or if my nmom did thank me it felt like a kind of forced trollish thank you with a smirk and a weird tone in her voice. We never say please, we never thank each other for whatever help or shit we get, we never even say sorry for mistakes.

I've been forcing myself to use these as much as possible with other people and it seems to slowly be working and it's becoming less forced and more honest. But I still can't seem to bring myself to thank my parents for anything. I just get a weird feeling of anxiety, I kinda mutter a thank you or something like that and hope they hear then I leave the room.
