Anxiety, perpetual sadness, and holidays

I don’t know why but lately I’ve been really nervous about holidays. I’m talking birthdays, thanksgiving, Christmas, Father’s Day, Mother’s Day, Halloween even. Every time I think about the holidays or celebratory events, I get a knot in my throat and this heavy feeling in my chest. I just feel like crying or hiding in the dark until it’s all over.

I don’t think anything traumatic has happened to me on a holiday. I don’t know what’s wrong I hate feeling like this.
