depression is painful
Sometimes I just have to "act as if" I feel better until I feel better.
If it is too debilitating I go to my food choices and try to narrow down what is wrong on that front. In my experience, too much of a certain food group or too little of a vitamin can lead to depression.
I have also had to take antidepressants.
Please try to talk to as many people you can.
I found out that only i could actually alleviate my depression. Wheter by exercising (when I can---I have dif-abilities0 or food choices or meds or meditation. I am responsible. The great energy force 9G*d, Goddess, Alah, whatever you call it) can not help unless i want help and ask for it.
