If there's someone there to hug, you need to tell them what you're feeling, not just ask for a hug, I think? People get immersed in their own stuff, not because they dont care but because they cant read minds.

And if it's a guy, they need Real Clear Signals, loudly, because thats how guys have been taught to be.

Ask for love. You'd be astonished how often that will work

why are you alone ,,, everyone should have someone ,,,
