Definitely try some earplugs, I personally like the foam ones that you roll up and then expand in your ear. If that’s not enough get a pair of over-the-ear hearing protection and use both together. Just be sure to have a vibrating alarm on your phone to alert you when your getting close to your stop. Then be sure to print a pillow and maybe a small blanket. Also put a lock around whatever bag your bringing and sling it around your arm or leg to prevent thefts if you have things of value with you.

Honestly aiming for sleep is probably the best thing for the short term. Trying to learn new skills or look for a new job/apartment while exhausted and stressed just compounds it.

Best of luck. It will get better.
