It's tough, Lisa, really tough. I can relate to some extent, as my husband and I are only children and we have no kids. We don't have much of a support system either. Gordon has me, but I've never felt so alone in my life.
Brian is right - you will find out who your friends really are in this situation. I have one friend I thought would be right in there pitching with me and I haven't seen her since Gordon's treatment began. Another one who lives a few doors away never even phones because she "doesn't want to bother us" and she "knows how busy we are". Translation - she doesn't want to deal with it. The friend who has been the most supportive is one who has recently completed 2 years of treatment for inflammatory breast cancer. You may end up being able to count the "true friends" on one hand, but they are worth their weight in gold. I really hope that you will find one person, just one, that you can trust enough to tell how you really feel. And you will find lots of support here. My heart goes out to you.
