You are supposed to get a yearly physical, right? What about a yearly mental? :) How many people check their mental health on a yearly basis--even if there does not seem to be a problem? Few people actually do this. However, I can think of at least one of my friends that does something like this.
Why go for a mental health exam if you do not need it? There are so many people that have stress creep up on them without seeing it. This is a great way to use the help of a professional to see if stress is becoming an issue. Also, it is a great time to look at what successes you have had the past year and what you need to accomplish.
Once you start a dialogue with a mental health professional, you will likely be surprised at the successes you have had and also those challenges that may benefit from a bit of consultation.
