There's nothing "wrong" with you at all Scampi. I sometimes think that Christmas engenders more pain than happiness. Stay strong, it will soon be over, and maybe, just maybe, one day the tide will turn and all this commercialised "ideal" Christmas nonsense that puts so much pressure on us will fade away.
Silverlady, my heart goes out to you. Your dad must have been very unhappy indeed, and to lose your mum too at that time must have been so tough.
