Coming on here is a good idea ! Lots of people log in ! Why not try chat ? Its a friendly place and if you are not too sure you can make your own room its easy to do and name it something nice ....
Also making sure you cook a meal for yourself is great to do too.
Plan before hand what and when you are going to watch tv if there is nothing on you fancy then get a couple of DVDs in.
I would also buy a Christmasy CD to play while on here so you are in a fairly happy mood it does not have to be a sad day.
