Hi. Your symptoms are seen with dopamine and serotonin deficiency. Been there done that and getting better slowly. I like this article on dopamine - I'm Not lazy After All. What a relief lol. So is getting rid of OCD! (that's a symptom of serotonin deficiency btw) :) I posted a link to another answer of mine on serotonin deficiency because it's longer than the info below lol)
