Toprol-XL and antidepressants

It's hard to describe all the side effects I think I am having from taking 50mg. of toprol 1x a day, at bedtime. Since taking it, I have heart palpitations,flushing, full body pain, sleep all the time. Feel without hope- so I guess that would be described as depression. I have 0 energy, or even motivation. I have become a hermit in my own house, have not gone out anywhere at all- the entire summer. At first I thought it was becuase certain terrible things were happening with my daughter- but now that has abated-BTW she's 47. So I don't think the way I am feeling has to do with that. I feel just ghorrible- worse every day. Don't want to do anything. All I do most of the time, is sleep, or pray that God will let me die- I have nothing to live for- or Please heal me. Finally I have an appointment with my Cardiologist-Internist this Thursday, and I will ask him to take me off the Toprol. Tonight I am not going to take it, nor anymore until I see him. Nancy
