OP has your H always been this "attentive"? I've found that all the therapy in the world, even for past significant trauma cannot deeply help when in your current, daily life, at home (the place you can't "go home from", unlike work) you are treated like shit on the bottom of your "D"Hs shoe.
It basically compounds the impact of any previous trauma, especially from neglectful and/or abusive parents because it's happening again in real time. The idea of EMDR is to process the trauma, to put it in the past where it belongs, but if a similar thing is happening in a significant relationship at present then the positive impact of the therapy is not very obvious.
I'm obviously not sure what you'd past is, but I want to raise the possibility that if the way you're currently treated by someone who is supposed to love and cherish you above all others, is an ongoing thing, then the source of your mental distress may not lie entirely within you. Meaning therapy can help with some things, but the impact of your living situation should be underestimated by you, and as a result neither should your "inability" to benefit from therapy.
Imagine if you had a partner who noticed you and how you were doing and didn't treat you like an inconvenience. Would that change anything? Possibly?
You do have a lovely sounding little girl. She obviously loves and needs you a lot. That is wonderful but in my experience can also be tiring. As much as you can let yourself feel her love. In a few - not many - years she'll need you just a little less for daily stuff and she'll love you just the same. Mothering becomes easier and a bit less tiring then.
I don't have advice re meds etc because that's all so individual. Don't give up though. Speak to the GP even if it feels like there's no point.
