Some posters since you mentioned an increasing disbelief have recommended that you pray for faith. I'll second that recommendation, and I'll pray for an increase of your faith, BUT:
It seems that you have a few intellectual premises that are incompatible with faith, because they're incompatible with reason. Faith is not a state or condition that "takes over" where reason "leaves off." You've probably heard it said that the faith is reasonable, but do not take this to mean that reason leads us to a gap, and then faith takes over so that we can make a blind leap over that gap into actual religion where reason ceases to function and faith takes over.
Stop caring about your feelings. If you went to buy a car, or a home, or something else, you'd (hopefully) have a fairly rigorous intellectual process that guided your decision; you'd want to know a bunch of details in the order of fact and reason to determine whether or not the car or the home was actually good in the objective order. When it comes to your very life and how you live it, the same sort of deliberation is made all the more important.
So go back to the reasons that you were Catholic in the first place. Find those reasons. Hopefully, you'll find that they were intellectual. If they weren't, then it's time to make them intellectual. And by intellectual I don't mean that it's time to go to the library and time for you to become a scholar. I meant that you need to have actual REASONS, not FEELINGS, that are informing your "religious sense."
If you don't have that, not only will you certainly not ever be religious, you'll never be much of anything other than a slave to your passions or feelings. For instance, if you were to marry, what will you do after the honeymoon ends (and it ALWAYS does) and you begin to "feel" ordinary and complacent? What will you do when the nice feelings of love and excitement and novelty in your spouse begin to wear off? If you only married them for those feelings in the first place, you're going to end up divorced. Again and again. You'll be sixty years old with several spouses behind you and kids from each of them, and you'll have taught each of them to just follow their feelings so don't count on them ever caring about you being in a nursing home because it's an inconvenience to their feelings to have to juggle your feelings, which by that time will be so overwhelming due to you have virtually no social stability, a scattered family, and your mortality sneaking up on you more gradually by the day.
So go back to the reasons why we're Catholic. Really basic ones. Does God exist? Why? How does natural reason show us that He exists? If He does exist, what do we know about Him? Do we know that he is all powerful, the cause of all things, all knowing, etc.? If we do, do we know that he has established a Church? If He has, which one? What are our obligations to belong to that Church and to live according to God's laws?
Each and everyone one of those questions can be answered without appealing to feelings. And really, they MUST be answered without an appeal to feelings. These are questions, believe it or not, that have already been answered by St. Thomas, and he's answered those questions without ever appealing to the need for feeling, sentiment, or blind faith. Look to him, and look to others who have shown through reason and natural philosophy certain basic, fundamental truths about religion.
Pray, of course. But you sound like you're beyond prayer, at least in the sense that short of a very strong influx of faith, you simply do not find the fundamental truths of religion AS SUCH to be convincing. Your problem isn't "just" with the Catholic faith, it seems to be with all religion itself.
