My boyfriend who is extremely depressed about a close friend dying of cancer has the following signs and symptoms that are really worrying me: complete loss of appetite, taste alteration (everything tastes bad), dizziness upon standing, nausea and vomiting, low blood pressure, tachycardia, insomnia, sweating, dehydration, sleeping all day and then insomnia and restless all night, feels like fainting. I can t get him to go the ER. Should I force it immediately? I know it s a stupid question but he is attributing everything to his depression.
