insecure

I have this nagging insecurity about me and my bros.

Somehow, it feels like,
they don't consider me as their elder brother anymore,
heck, probably not even in the first place.

They no longer talk to me about what they use to talk about,
rather, conversation has always been revolving around geog and school.
My attempt to ask how are they,
always felt awkward and short.
The converesation they initiate,
seems to revolve around their test, exams, or asking me to help them look for / tell mr/mrs/mdm/ms XYZ.

Perhaps they don't feel comfortable.
Or they don't feel that close to me after all.
Perhaps it's just my wishful thinking,
and something for them to use to get benefits.

If any of my bros read this,
yes, this kor of yours is a insecure person.
I'm not doubting you.
I just need confirmations, affirmations, whatever "tions".
All along I'm a person who is reserved by nature,
and given my status,
I can't ask you all this question openly.

I just need a confirmation.
It's ok if you say "I've not considered you as a elder brother"

Cause I don't have much time left with you all.
