Moved to a new shared apartment

Hello,

I am 30 years old and  recently diagnosed with Autism. 

It is a month I have moved to a new shared student housing which I have a private room with shared common area/ bathroom/ kitchen.

I am so anxious to go out of my room and use bathroom or kitchen. It is been terrible with noises as well but I soundproofed my door two days ago. What can I do? Some days I can locked up in my room for 13 hours and it is painful for me.
