So a friend had a lot of family issues, family illnesses over a long period. She and I would commute to work in the morning at the same time so she would ring me on the way to her work and basically it was a time for her to sound off. She was under tremendous strain and I didn't always want to hear it but I did. So things have settled now but I have changed my job and moved, hence my commute is shorter and I don't have to leave so early in the morning this has put us out of sync time wise. But my friend has continued to ring me at the time she commutes about an hour before I need to get out of bed. I am a horrible sleeper and relish the lie in. I also work alternate days at home, meaning I could roll out of bed 15 minutes before I need to turn my computer on at 08.45. I have sort of whittled her down to not ring on these days. I have told her I was off this week because of unpacking my stuff with a house move. She has still rung me ...the first day I was in one of the best sleeps I have had in months and she woke me up, I sort of snapped I was off and she said sorry and ended the call. She has done it again today. I didn't answer the call and she rang a second time but I ignored it again. This is an ongoing thing. I have told her I'm a terrible sleeper but she persists. It has turned into phonecalls all about her. She has been a lifelong friend and is incredibly kind in so many other ways but all of her personal troubles seem to have got her into a rut of being self consumed. How do I deal with/say this without ruining a friendship.
