Moosey, I've just been there myself on the Morphine Terror Trip this last few weeks and I am so sorry you are going through it yourself. It's the most horrific drug when things don't go well...
You do come out the other side, try to hang on to that. The way you feel now might be horrible, but it will get better and you will find yourself forgetting much of the crap you've gone through.
It saps your strength and energy and hope, but those things will return, and you'll smile. Honest
I'm regaining them after my month of hell, and you will too. Just look after yourself, eat well, and don't be afraid to ask those around you for help with the little things.
Take care, and remember you're never alone.
Bram
