Hey Id love to help!
step one:
go to profile, and click friends list
step 2:
there should be a little bar thingy above a button that says add to friends. type in friend' s name then click the add to friends button. it should send a message to your friend asking to be friends.
if someone is waiting for you approval, than go to Approvals and markt the person who you are approving. above their name their should be a button that says approve. click that.
hope this is helpful!
