Sorry to read here and on msn m8.
I was nearly made redundant (well I was made redundant and managed to secure another job in the same company in the nick of time) and I know how you must be feeling.
Like you, put everything into it, and then, nothing as much as a thank you

I am not working anywhere near as hard now.
If I were you, I'd take the other job, bite your lip and bear with it while you find another job... Won't be much fun, but at least you'll be taking some money away in the mean time.
If the package is good, take it and start looking asap.
Good luck Stu, feel for you m8.
