I'll never forget how sad I was that my sister didn't call me after we told her about my cancer. A few weeks later part way through my chemo I received a package of scarves and beanies that she had knitted for me. I called her to thank her and she was so excited to speak to me.
Apparently my mother had told everyone that I didn't want to talk about my cancer and so it would be best not to call!! Huh?? I had mentioned to mum that it was hard telling people because I had to keep reliving my shock and grief when they reacted to my news and she decided that I didn't want to talk to anyone. Hmmm...
I was also surprised that an old friend seemed to be avoiding me but it wasn't until I mentioned this to another mutual friend that she commented that she was avoiding her too!! Opps - turned out that she had just discovered that her husband was having an affair which led to her marriage breaking up.
Sometimes it not about you.
Call you friends and family if you want to talk to them. Ask if you want someone to do something for you. It may be that they are trying to give you space or are worried about disturbing you or simply don't know what to do or say.
