The Christmas blues, as they're called 
They hit me hard, and have done so for the last 2 years or so. I'm not really sure why.
I'm a huge fan of the Christmas season. I love how jolly everyone seems (even the grumpier people seem less touchy).
I just find it so hard. My mood gets so low that I often feel a deep sense of sadness and loss. I miss it all so much. I feel somewhat tearful thinking about 'the end'.
I cheer myself up on Boxing Day by heading out at 5.30am for the sales (I have in mind what I'd like before going). But that's not 'the end' of the Christmas season so isn't so bad.
Come New Year's when the clock strikes 12, I absolutely bawl my eyes out. I cry about the whole year, how bittersweet it is that my baby boy was 1 in November and now he will be 2 in 2019!
I just can't handle it all. All those big emotions at once. It's not even 'bad' emotions that I find difficult to handle.
I often go off the rails (in my head only), when something huge but positive happens. It's like I get a bit stuck.
Any advice?
