do you have non sensitive/emotional parents?

my parents are both really not sensitive or emotional and im not, I am very sensitive and emotional.I grew up not hearing them tell me nice things like I love you your doing grate. I really want to tell them I love them because I never told my grandmother I loved her before she died. my grandpa died too. I really want to tell them that i love them but i asked my mom why she never tells me she loves me and she said because i dont want to say something thats not true, no one realy knows what love is people are incapable of loving. I really dont want to believe this but i am having a hard time getting myself to tell my mom i love her. I think she will think im lyeing to her or just saying it because im supposed to say that. i just dont know what to do.
