I would like some insight before I go to the doctor?

Hello! SOO~ I recently dislocated my shoulder on Wednesday (1/14 aka my birthday) just by rolling on my bed. EMS came and as they were splinting my arm into place it popped back in so I decided I didn't need care. However, later that night my mom saw my shoulder and my shoulder is about a half inch to an inch lower than my other one; lower than it was before. My shoulder blade is lower too and stick out further. I am too scared to try do-it-yourself-at-home tests because it hurts to raise my arm halfway. I feel a pop and get shattering pain. I am going to the doctor this Wednesday but I would like some insight on what it could possible be. :/ I can't take my sling off for more than 20minutes or else I get a huge amount of pain in my mid back (where my shoulder is currently placed) up to my trap muscle and all the way down to my ribs just under my chest.

I think its serious, but I'm not a doctor. Could this be a rotator cuff tear? Thank you!

Also, don't be like "You need to go to the doctor ASAP" because Ik but due to circumstances, I have to wait till Wednesday.
