Hi AB, welcome! 
I’m a recovering sex addict as well (porn and masturbation in my case but the same basic problem of using my sexual behaviour to change how I feel, and not stopping even though I wanted to).
There is a path out of this. 
It helps to have help. You’re here sharing on this forum partly because you realized you couldn’t do it alone. (No one does it alone. If someone can recover alone, they probably were never really addicted. It’s like getting free from a cage. You need help to get out.)
There’s a few different ways to get help. This forum is a nice way to connect with people who are in recovery, and a great place to connect and support (like here Checking in daily to maintain focus #42) and have some fun (like these Post photos of your pets #4 and Foodies Unite #4 (trigger warning food) DON’T GO BACON MY HEART! and Post your most inspiring photos of nature #3 and there are many other interesting threads).
Me personally I gained a lot of insight and I learned a lot about practical steps from my sex addiction recovery group.
I was nervous going to that group my first time but I was welcomed warmly and I haven’t looked back. Some of my closest friends now are people I met in that group. We take walks, have BBQs, coffee, etc. I feel really blessed to have this in my life. (I didn’t before. I was so alone, in myself and in my world.)
I can hear you’re nervous about opening up about this. Sex addiction is about equal numbers for men and women, but for the women the double-standard sexist expectations of the world are there, so, many women feel deeply ashamed and conflicted about their struggle, and hide it, often in other addictions (like alcohol). My heart breaks for the women who go years and years, decades even, sometimes their whole lives, without getting the chance to be free.
It takes courage to step forward but I promise you it is worth it. I promise you will find other women in recovery when you search (at the links below you will see “women only” is a common format for meetings; take a look at those). I promise you will not regret this. I know you’re nervous. That’s ok. You can be nervous, but don’t let that stop you. (The nervousness will go away I promise; don’t let it be a chain holding you back.)
There are a few groups that can help you with a specific focus on sex addiction recovery. I’m linking online meetings here & I’ll put the in person ones below.

There’s a good collection of in person groups here; many of these have online too if you search around:
Keep moving forward and ask yourself, “what’s the next right step” - take life one step at a time and just keep focused on that next right step, next right step, and you’ll get what you need, I promise.
