Maybell - I'm just catching up after a longer-than-intended absence, but wanted to say that you've been in my thoughts.
It sounds like you've been having a lot of ups and downs, and I think the best thing you can do right now is to take care of yourself - if you're overtired and stressed emotions are going to be a lot more of a roller coaster and it's going to be a lot harder to step back to get a broader view and to catch your breath a little. And doing what you need to do to feel better - taking off the ring, not wearing any reminders of him - is good, too.
For now, I hope you can have a bit of time to wind down and some solid sleep tonight. It won't fix everything, but it's likely to put you in a better place to deal with whatever tomorrow brings.
