My 2 cents, for what they're worth:
I have been in your exact boat. It is not a good place to be.
It IS your wife's job to help you, as two became one. My spouse didn't help me and it was VERY difficult for me to tie a knot in the rope and hang on all alone.
Most priests don't have time for such a person, nor are they trained properly in how to handle such a person. Can't tell you how many spiritual advisors I went through before I decided to leave them alone except in the confessional or when he asks how you are doing.
I will get slapped around here for this, but I enlisted a Christian counseling group for help. Couldn't find a Catholic one. Had counseling twice a week for years to slowly help me heal. The group made healing slower than if I had a one-on-one counselor, but it was important for me to see that i was not alone, that there are others who are going through what i was. Also, others were in a different position along the path of healing, so i could see i CAN recover.
While healing, it became very difficult to pray any rote prayers, so I just started noticing God everywhere: in the movement of the trees, in the beautiful sunsets, in the smell of the flowers, in the feeling of a warm hug from my child, in the taste of yogurt, etc. This is not to say I didn't pray. When I noticed such, I always said, "thank you, God, for loving me. You know I love you." During the day I also thought of the Holy Family and especially St. Joseph.
It has taken a long time, and I still go to group counseling now and then, but I am back. I am healthy and my Faith has never been stronger.
I hope you find your path to healing. God loves you. That is ALL that matters. Love him back, as best as you can right now. He understands you are human.
