My driving is becoming horrible

I have always been a great driver, I use indicators religiously and always on point with the laws. Recently i have become super aggressive driver & could possibly be because of the traffic lately. I have started jumping the queues and have started to hop lanes alot.

Its making me worried and making me lose my sleep thinking about all of this, is there a way to fix it or possibly start leaving early for wherever i am going?

just an year ago i wouldnt even dare about jumping queues but now since all the cars are doing it and waiting in line gets you nowhere i have started doing it too :/
