Are you on any meds? If not, the amino acid DLPA [DL-phenylanaline] would be something to try as it's used by the brain to produce dopamine and norepinephrine. Both neurotransmitters are what make life worth living, and without adequate in the brain, life is utterly hopeless. I take this for the depressive side of my bipolar 2, and find that so long as I take it, life is good. If I don't, the hopelessness reappears in my life.

Here's a brain function questionnaire that will show you what neurotransmitters and related amino acids are related to which emotions and feelings.
