Sometimes it's ok to sleep the day away, @utopia, as long as you are taking safe levels of medication. I remember being in the same place as you are now, quite a few times. I would take the calming tablets and just lay down and let them do their job... it was a nice surrender and an escape. Sleep can be so beautiful. When you wake up, I hope you can put on some relaxing music or a nice, uplifting DVD. Or perhaps call a friend of the phone.
I am thinking of you. I hope you are able to get back into hospital, if that is where you would like to be.
I have never been hospitalized due to MI, but when I was at my worst, I kind of wish I had been. I would have been nice to be looked after and feel secure. I actually kept working right through the worst of my depression, which is amazing when I look back on it... I wonder why I felt the need to do that? I put so much pressure on myself.
Eventually, I fell in a heap and called in sick one day to work, and then just never went back there. They were pretty sympathetic, amazingly. I can't remember what b.s. I told them now, but I couldn't care less about the job by then, anyway. 
I went home to live with my parents for a while, but they were not too sympathetic- I was pressured into getting another job straight away, by them. So much for being cared for- I would have been better off going into hospital and being looked after by strangers!
My parents thought "working hard" was the cure for every human ailment! That's probably why my sister became a workaholic and I just became rebellious.
Sending you kind thoughts, @utopia.
