Are these correct?
1. It has been a long time BEING away from Home/you/facebook...

2. Please just keep it dark, dun tell anyone, You are cooler BEING a mystery

Both these sentences are not so common to me.

Number one seems to be OK in informal English.

In the second one, do you mean "you are cooler by being a mystery"? Although a bit unusual, could be informally OK too.

I think it is better to hear a native speaker's point of view.

1. It has been a long time BEING away from Home/you/facebook...
You need a subject who has been away (not a grammatical subject).
1. It's a long time that I've been away from Home/you/facebook...
Being away from home/you/facebook for so long has made me miss it/you/it.

2. Please just keep it dark, dun [huh? Do you mean don't?] tell anyone, You are cooler BEING a mystery
Yes, "you are cooler being a mystery" is OK
