Luckily I'm kinda pagan, so I see all the time between about Dec 20 and Jan 7 as the time of the solstice. Plenty of time in there for celebrating with any family group or individual (blood family or chosen family).
That said, if you're a secondary with no primary of your own, I can see how you could feel lonely and left out any time, but esp during the holidays...
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
