A few weeks ago my partner suddenly ended our relationship. Since then I have no appetite, cannot tolerate much food, have had ongoing loose stools, often feel thirsty but cannot quench it, have a lot of sleeplessness, often feel jittery and wired up, get a racing heart, often feel headachy and get warm flushes. Waht's going on? I'm know that I grieving and getting bursts of adrenaline but is there a medical approach where I can take something to get thru this awul time.
