Wow I can only imagine the pressure you feel I hope things work out for you. If it is worth anything maybe next time after you have secured a job it cant hurt to continue looking. That is what I did, I almost took a job somewhere else but reversed my decision last minute but that employer left the door open for me in the future. So if something happened I have somewhere to go right away. I guess my point is to have some sort of plan B no matter where you are in life. Best case is to be self employed though!
