ok ok I hope you called 911 if you didn't call them and tell them that

in the meantime try to find how deep the wound is if it's not too deep then try and find something that can cover up the blood

then find something that at least can stop or help with the bleeding and see if your mom is still breathing if her breathing slows down call 911 again tell them to hurry over and tell them about your mom

ok ok uhhhhh do you have a med kit if you do find some stitches

if you have stitches then follow this : Take the stitches and the needle put the stitches through the needle and then poke the needle on one side of the wound then go over to the other side and repeating with that one string don't just start over and over with new strings or cut the one string. After you tightened the wound tie the string and cut the remainder off from the needle

you have to this or the wound is gonna get worse and please trust me but before all that put some alcohol on it I took med school
