I was just about to post something similar..

There's nothing "wrong with you". Is it possible it has something to do with having a more "surface-type" relationship with these people? Maybe I'm misunderstanding your post.

I'm more inclined to think people often tend to turn 'away' from support rather than 'reach out' to it, whenever they're going through a difficult time. Or maybe they'll reach out to their closest person (a family member or best friend) and put everything else on hold.

Try not to take this personal unless you truly believe you've done something to offend.. and in this case, address it.

Keep putting yourself out there. Reach out to the unsuspected.. you may make a new friend.

I, too, struggle with making connections. I suffer from a lot of anxieties and situational circumstances that keeps me guarded.. so I get it.

Big hugs to you! Thank you for everything you are doing to help others.
