I got a job offer but, i'm not sure if I should take it. 
How come?
Similar pay, possibly more room for advancement but, I don't know anyone that works there.   So I could be moving over to a place with similar pay  benefits and stepping into some sort of fresh hell
That's definitely concern. Is there no more room for advancement at  your current job?
Not unless we have an ebola outbreak or people start getting cancer.
