My elderley father has terminal cancer and is getting worse. My Mother is his carer and does a brilliant job but I worry about her. I live very close and they always used to come tome for sunday lunch. My father will go ot for lunch but he doesnt want to come around to me anymore. I am doing everything they say but find it so hard to cope and just get on with my life. I have frends and it does help but you just feel they have their own lives also and dont want to burden them with your worries or concerns.I have this horrible sick feeling in my stomache that just wont go. I just feel so helpless
