> At this point I feel I just can't win against myself.
Because you can't, only God can. I used to be in a really bad situation with the faith, I was raised Catholic but for a very long time I believed only out of habit, not out of choice. I only cared about "happiness" and my own pleasure - I just wanted to watch porn, masturbate, eat tasty foods play video games and watch videos. This was my primary goal in life and with each year it got worse, I wasted more time on these things and the material got worse and worse. I was weak - physically and mentally, socially inept and not passionate about anything.
For a very long time I saw no reason to change anything because I was satisfied with this. But eventually, a time came when my sins got so bad that I started to question my choices. There wasn't some huge breakthrough where I suddenly turned into a saint, but I slowly started seeking other things. My excessive hedonism left me feeling burned out and pathethic. So I wanted to find true, actual happiness. I wanted to find love, which at that time to me meant finding a good girl to love. So essentially, I was still just looking for my own hapiness, but through more virtuous means.
However, this was the beginning of my journey to the faith. I figured that the best way to find this girl was to ask God for one, then serve Him and do what He wants so that He would give me one. I started trying to stop sinning, especially masturbating. For the next 5 years I've been struggling, rising and falling with ups and downs. Sometimes I would go months without sinning, yet sometimes I would fall into even worse things than before.
But during that period, after every time I failed and went back to my old lifestyle I eventually confessed my sins and repented. And each of these times taught me something, and the most important thing I noticed was this - even thought I kept failing and betraying Him, God showed me mercy every single time. No matter how bad it got, He always accepted me back and kept changing me for the better. With time I began to realize that it's actually in God that I can find the one, true fulfilling happiness. I started learining more about the faith and improving my spiritual life and everything has been getting better.
I still struggle with sin and other things, but it's incomparably better now and I know I'm on the right path and it gives me true happiness. So all you really need to do is stop depending on yourself, trust God and seek to understand Him and do His will. If you set God as your number one priority, everything else will fall in it's proper place.
As for denomination, the Catholic Church is the one true Church founded by Jesus Christ.
Don't be bogged down by your failiures, they are only temporary and can always be changed. Submit fully to God and they will be.
