I hope you are feeling better today, hugs, and pleased you enjoyed the folk evening. It sounds like a lot of fun! As does Smile's Christmas tree on the roof terrace - at least Santa won't miss your house when he passes by on his sleigh. Just remember to put out some carrots for the reindeer and a glass of something for Mr S(anta) 
Thanks for your kind words Starlady. Yesterday was a very happy occasion as it was my graduation and I was accompanied by my DH and DD2 and DD3, who made it very special for me. They gave me such a loving card and a gift which was so carefully chosen, as it relates to the subject which I studied. I was actually quite anxious when I woke up, hoping that it would go well, worried that I might trip up or something when going up to shake hands and collect my certificate. I was probably at least as anxious as the first time, many moons ago. DD1 was not there, obviously, as she is due to give birth any day, but at least she sent a good luck message.
And that is the thing about estrangement, it can eat away at your self-confidence - or, at least, in my case it has. You feel that if the person you gave birth to, gave your heart to, loved unconditionally, would give your life for, can just discard you, then you must be of little worth. So, for me, it's essential to treasure the precious moments with other family members and friends, who make me feel worthwhile and special. I try not to let the estrangement make me doubt myself or contaminate all that is good in my life, although it is not always easy. DH has been such a support, in his quiet way, with endless reassurances that I am not a bad person or a bad mother. When I started my course, just over two weeks ago, it was at the lowest point of the estrangement and I had to make myself carry on, as sometimes I was so upset and tearful that I could not concentrate. I just felt like giving up, that it was all a bit pointless, when DD1 was the focal point of my feelings and thoughts to the extent that there was no room for anything else. Apart from being a lovely family day, yesterday felt like an achievement, as much in a realisation that I survived the last couple of years as anything academic, so it felt like a turning point in a way.
Muffin, I feel so desperately sorry for you at present. My DD is also very much under the influence of SIL which is inevitable if someone is with a person 24/7. It may not be about money or difference in lifestyles but, if it is, hopefully time and maturity will lead your DD to a different perspective.
