Beth,

No - it is not selfish!!! Depression can be so overwhelming and color everything in your life. Trying to save yourself may be all you have energy for right now. My therapist used to tell me this story about being on a plane with my small kids. If the plane is going down, do you reach for your own oxygen mask or help the kids first? You have to put the mask on yourself first, to be sure that you are strong enough to help the kids. This sounds like one of those cases.

However, if your friend is also depressed, you might find that you could boost each other by sharing and commiserating...or even finding some things that make you both feel better and motivating each other to go do them.
