Don't beat yourself up for e-mailing your H. Each of us has done something like this. It kinda goes with the territory but you will get better at detaching as time goes on.
The crying WILL get better. I had myself a little crying jag today and now have a little Crying Headache (but not the eyes, thankfully!). I find that when you are doing well you WILL suddenly get a wave of sadness. It is human and it is better to get it out. If you suppress it you will have to deal with it later. I just realised that you are on meds but perhaps you can talk to your doctor if you are concerned.
No, the bad days won't ruin your progress. It is a sucky situation for us all to be in but it WILL get better with time. That is all I can say right now.
