Rock bottom sucks and (symptoms).......?

It sounds like a malignant mass causing you trouble. The one thing that would be most effective for you is what you already mentioned - a doctor. In the mean time to elevate your mood and provide some regulation in you body, try these three things: a high (900mg EPA & DHA) omega3 complex three times a day (providing you are not on blood thinners), 5-HTP (produces serotonin and melatonin), and L-Tyrosine (regulates thyroid). Hit up the search for further information on any of these!
