This time of year can be bring out almost any emotion in us. I believe a lot of people feel depressed during Christmastime. When you see your family falling apart then it has to be awful.
I think it's important to surround yourself with people who love & appreciate you. Stay away from those who talk negative. Listen to peppy music(not any old country sad-love songs), read inspirational books (or whatever you can lose yourself), and watch comical movies (no serious family stories). This action is you protecting yourself. This has to be planned. You know what you will be facing, so get active and be prepared. Go places where people are happy! You may not feel like it, but you must try.
If you begin to feel too much dispair, let somebody know you need help right then.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
