I wonder if its something to do with my diet . Ive heard that can influence you.
Yes, diet can be a
big factor.
Whatever the chemicals, and minerals, and vitamins, and colorings, and preservatives, and everything else is in the food will be absorbed by your body.
And then your body tries to get what it needs out of it all. If the right things are not in there, or there are too many artificial chemicals getting in the way, it's not going to work quite right.
My Mom was a Dietician, Nutritionist, and all, she could give all the technical details.
All I can do
(and I hope to god she never sees this!) 
is say that she was right - food makes a difference.
Best place to start is the old saying "A balanced diet in moderately sized servings"
And, it's always possible to be down because you are down, and that's just the way it is today.
Hang on, you'll get there.
Do tell yourself that you
can find out why and then let it happen
