Concussion

At soccer practice this morning I fell and slammed my head on the ground then was kicked in the head right after my head bounced up because my teammate didn’t look down to where the ball was. And I had to take a concussion test. And it came back with me having a concussion. This happened around 6:45am it’s now 8:50am and I’m super drowsy. When can I sleep and how can I get better faster? Can I go to work today? I work at 5pm. What are my restrictions?
