I am sorry to hear that things are so hard for you. There are some good suggestions here for the light problem. Taping cardboard onto the windows until you can get some black out curtains from walmart.

It does take a while to settle into a new place. I find that having a radio on inside my place helps my brain to focus on the inside of a place rather than the outside. Also while getting to sleep I have the radio on softly (White noise) to also change my focus. Ear plugs are a great idea too. Do you have an eye mask that you could wear to block out the light while you are sleeping?

People kept on telling me that I would get used to the noise. It does get better even though I am still aware of it.

Are you in contact with your doctor still? Maybe you could take some valerian root to help you sleep or ask if the doctor has any ideas. Releasing the tension is hard. Can you watch something sad to help you cry?

I do hope you feel better sooner rather than later.
