Depression Again?

Recently, I have put together some facts. 

1. Two weeks ago I had immobilizing back spasms.  It took a good three days of rest, heat and muscle relaxers to get my back to relax enough to go back to work and function. 
2. One week ago I had a debilitating migraine headache that sent me to bed for two and half days.  After taking a migraine medication and many Lortab, I was able to get it under control, even though my head was sore for days. 
3. Prior to that I had seen my psychiatrist and he had increased my medication ever so slightly because I am having increased depression. 
4. I have been having chest palpitations for the last several weeks and have been having to take my Bystolic to control it. 
5. I cannot get enough sleep!  I am sleepy all the time regardless how much sleep I get. 
6. And not least of all, I am having great difficulty writing, coming up with subjects, and just the whole process itself.

The fact is I am probably more depressed than I realize and it is now manifesting itself in physical symptoms.  Now that I realize this, what am I to do?  First thing is first, make another appointment with my psychiatrist.  Second thing is that I should be exercising, but I know that isn't going to happen!  I can improve my diet, if that will help, cutting out sugar and decreasing my caffeine intake dramatically, eating a well-balanced healthier diet.  I have my vacation to Mom and Dad's coming up in three weeks and I know that will do me some good, plenty of rest, relaxation and laughter.  When I get back, I need to make an appointment and start see my therapist again.  Any other suggestions?
