I feel for you, I really do. Sometimes not getting through to your other half what's really going on in your mind can cause frustration and eat away at your confidence.
I don't advise this, but I did it maybe twice in seventeen years - I had an absolute meltdown in front of my hubby, I screamed and sobbed alternatively till I got my message across. He stood and listened, I calmed down, and then we talked properly. ( the reason for it was I was desperate for a new cooker, and a new fridge, the ones I had were over twenty years old, and did not work properly, in fact were down right useless and dangerous.). As I said I don't advise, but it did make us talk about the issue, my hubby is a man who insists things have to 'break' first before we buy new. Anyway within days we had a new cooker and fridge freezer.
There may have to be a meltdown again in about six or seven years, I hope not though, as I am such a calm and happy person normally.
I also think don't sit inside looking at your walls, do something, anything to take you slightly out of your comfort zone? It will give a boost to your confidence levels, then you can build on that.
I do hope there will come a time for reconciliation with your daughter.
