Hi Lucy and again, welcome!
I am sorry to hear that this is a challenging time of year for you.:( I understand how significant dates can be very difficult to get through.
I love your idea of focusing on the positives and practicing gratefulness. This is proven beneficial in managing anxiety.
Here are some therapy worksheets that will help you to do this, while also working through difficult thoughts and feelings that may come up still.
