What do you do when you start falling in love with someone you grew up with but she thinks of you as a cousin?
all you have to do is tell her how you feel about her. every girl likes to hear what a guys thinks of her! maybe take her to a movie or somewhere where you are alone and just tell her evrything! you forget her and look for someone else
Make sure he knows you care about him and be there for him. Tell him you are willing to take him so see someone about these suicidal thoughts as he might need to start using medication. It is important to tell him to call you if he ever considers going through with it, he will need someone to talk him out of it.
I'm going to assume you don't like your cousin and that's why you need helping picking nice things about them. Obviously I don't know your cousin but first when you want to compliment someone you start with there look, maybe your cousin has a unique style, if not what are they talented at. Everyone has something they're good at. What are they interested in they could be really devoted to a love of country music and then you could say that you're impressed by there devotion.
