Can depression cause constant nausea and loss of appetite?

Have any of you experienced appetite loss and nausea every single day for months due to depression?? Ive lost so much weight, had several tests that show im fine except low hormone levels....im afraid to take antidepressants cause the last time i took them they made me feel even sicker. But if it is depression i may have no choice. I have been in counseling for years and its not helping....i do have some underlying anxiety, but mostly cause i feel so terrible all the time and i dont know what to do!
