My sister (15) and I (18) are very close but i don't know whether i should tell her not. She has seen my anti depressants but i just tell her that they are tablets for my stomach. I am pretty sure that she knows that there is something up.
I told her i had depression about 4 years ago but she always brought it up in fights and always said that i was pretending to have it

she does deserve to know, but i'm not sure if i should or not
please help!
