That said, there is an important lesson here. Tying one's identity to one's place of employment is a losing proposition. You can feel loyalty to your team, your colleagues, perhaps even your manager. But loyalty to the company is misguided, it will not be reciprocated. You need to put yourself first and treat this as a business transaction that it is.
At the end of the day, this situation sucks, but believe me, it won't be long before it starts fading and mattering less and less. Wish you the best.
