Deep (accidental) cut care?

*possible trigger* Last night I was Trying to wash a plate. The plate broke in the sink, and I reached in to pull out the glass. A piece nicked my knuckle, I jerked my hand out, and my left wrist caught a piece of the plate, leaving a 2.5 inch long cut deep enough to see fat coming out of it. I literally slipped in my own blood scrambling around trying to find something to make a tourniquet with, and also smacked the back of my right ankle on I don't even know what. I got six stitches. Basically, I'm asking if anyone has any knowledge about how to care for a cut that deep? It keeps feeling like it's bleeding under the bandage, and I don't wanna look at it 😣
