The only person you can save is yourself.

Let your friend know that you love and care for them, but that you've got your own issues to deal with.

Then create a safe buffer between you and them.

It's sad that sometimes we have to let people go from our lives so that we may save our own, nevertheless it has to be done.

As you get healthier and stronger, you'll realize this is for the best, but damn it hurts bad when you have to do it.

The good news is, you'll meet and make new friends along the way.
