I do. It takes a lot to give that amount of yourself to a friend. Be sure you choose those people carefully because it's easy to get burned by someone who doesn't deserve it. It happens very often and it will rip your heart out every time. But when you find someone who truly deserves it, like I have, it's amazing what you'd do for them.
finding the truth in this one, when you are at your lowest you really do find who truly care about you, keep those people forever! Some with good intentions can't follow through for one reason or another. Feel sorry for those people for being unable to stand up for themselves (and for you), and move on with those who can :-)
