Big Question

My big question is: Can love truly save a person?
I'm interested in this because of many reasons really. I've been in love before and I know that being in love saved me from many different things including myself. Being with another person that you love is a completely life changing event and I know for me it was a saving experience. I want to know whether this is always true. In medicine this year we had a speaker who spoke on holistic medicine or "alternate medicine" and this interested my big question even more. She talked about the importance of taking care of your body, mind, and spirit and told stories of people who had cancer and recovered through the power of finding someone they loved. I wonder if this can truly happen and would like to read literature that can prove this to me. I'm usually an optimist so I hope that I can answer this big question positively but there are already some works we've read that make me doubt that love could truly save.
