@MaNaAk - I think that would be a bit of a "busman's holiday" for
@Ineedhelp as she already works in a centre helping people with their problems, even though it's not a charity.
It's a shame her niece hasn't thought of her being on her own but young people tend to be a bit self-centred and she wants to be with her boyfriend (?) and friends. I hope she is sharing in the household costs and that
@Ineedhelp is not having to bear it all.
If it weren't for my brother, I too would be on my own at Christmas as you find that people you know want to be with their own families at that time. I personally think it is all overrated even if you have got family to share it with. They often fall out at this time of forced jollity.
If you can just get through the day - perhaps watch a boxset and buy yourself some nice things to eat, laze about and just enjoy the time off. The day will soon be over and you'll find people are not in such a good mood afterwards and are worried about all the money they've spent.
One other thought - does Christmas mean anything to you spiritually - you could go to a church service - maybe you know people there? That after all is the real meaning of Christmas - sorry if that sounds a bit preachy.
