Taffy I do understand how unhappy you are and I am sorry for the illness, pain and sight problems that you are enduring.
It is hard for you that your daughter feels the need to withdraw but if she has told you that this is to protect her mental health then she is clearly struggling too in her own way, which could be for many reasons.
It is your husband who should be caring for you and helping. The fact that he has been verbally and emotionally abusive to you does not make your daughter a viable alternative for support for you, just because when she is there he doesn't do it.
I do think that your resentment/hurt/anger is more appropriately levelled at your husband than at your daughter. Be careful not to drive her further way by focusing on what you want from her rather than on what you DON'T want from your husband.
I hope your health and circumstances improve.
