Noise where I live and wanting to move

I have mentioned this issue many times on this forum, but things are coming to a head. As you may be aware, I was having significant issues with light disturbance from the adjacent street-lamp despite having black-out blinds, thick black-out curtains and net-curtains. Anyway, while the light still shines harshly at all hours, my Dad has helped me out with a one hundred pound black-out blind/shutter, which fits right across the window, thus almost completely solving this problem. But do I now get a good night's rest on most nights? The answer is a resounding 'no'; and this is because of noise and living next to a through-road.

Because this flat is my very first experience of living independently, when I moved out I was naive enough not to consider possible noise issues from the street. This is because I previously lived  down a quiet residential road, and my parents did not mention this issue when I moved.

Anyway, this week I have been woken up by students and twice by a car revving its engine. Last night this said car woke me up at 2am, and I could not get back to sleep, therefore only managing about three hours!. I am exhausted, and this is re-occuring theme. Therefore, I want to move because I cannot put up with this for much longer, and I currently dread going to bed because I know that noise will disturb me. Even when it is quiet, I am waiting in anticipation for the next noise-intrusion and this is affecting my quality of life.

I have tried ear-plugs and they do not work.

What can I do? I have a CPN and a support-worker.
