Had a really bad day today driving

Was driving my friends out to the West Mall, CCK area. Wasn't too sure of the road so had to change lane quite abruptly a few times and there was a hell lot of traffic lights. Got pretty frustrated and chiong a few yellow lights. Everything seems to be going wrong. The red lights, pedestrians, motorcyclist and other cars seem to be like against me.
As I continued driving at a junction near West Mall I saw an accident and a few ambulance came. Then I realise what could have had happened if things went wrong for me. Had a really bad day driving and its like a rolling snowball, getting worse and worse. End of the day, had to stop and really cool down before sending my friends home.
Paiseh and sorry to all the people using the Bukit Batok area if you meet a bad driver and hope everyone will calm down and drive in future and not get so frustrated coz it will only make things get worse.
And thats my bad day.
