Anxiety is a Creeper

I keep feeling anxious because of the Christmas holiday.  I keep projecting about faking the happiness when around friends and family.  What if I have to fake it, but what if I don't.  If I could just stop my mind and trust it would be so much easier.  The thing is, since I have all these anxieties and concerns, I assume my husband does.  Are we talking about it enough?  Are we being transparent?  Does it even matter?  Oh the skeptical pessimist I have become.  I don't like her, but I feel I need her to protect myself from anymore emotional harm.
