I am home from college watching my younger sibling after an attempt and want to know how I can be there while still giving them space. He locks himself in his room or plays video games, and want him to be able to reach out if he needs me to help him or if he needs something from me. I just would like to know what would be beneficial for him and what things I could do.
I started off my just texting him and giving him 5 options of how he is feeling and what he needs from me, so he can just answer with a letter instead of having to reach out of his own. I just said choose one of these: 
Today I want:
A. To get out of the house
B. To see a friend
C. Some alone time because I have low social energy
D. Not to be alone because I may be anxious or sad
E. To hangout together while we each do our own thing but have you check in with me 

Do you think that is alright to start? How can I be there for them when they do not want to talk?
