Resign or not to resign

My assistant manager called me yesterday night at 12.30 am... He asking me whether I want to take back my resignation letter and would like to transfer to rainforest fight back show... Haiz.. My manager asked me last Friday.. But I haven't give them the answer yet.. Now I'm on my way to meet them to tell them about my decision.. Which is, I will still resign and will not accept their offer... I know they still want me to continue working there but I've made a choice.. I don't want to work in that type of environment.. No one understands the shit I'm going through there everyday.. I really appreciate their offer.. Coz almost everyday, they will ask me to not to resign... I'm so sorry to disappoint them.. But I need to move on with my career and life.. My assistant manager advises me that economic is going to hit Singapore and its going to be hard to find job out there.. They didn't know that I've a lot of job offer out there waiting for me.. It's better for them not to know where I work or people may destroy my career that I'm going to build from scratch..
