So this isn't me severing myself from Judaism, either. I still love Judaism and Tanakh, but it's not mine.
Your OP is a great account of where you’re at in your spiritual journey and why you’ve moved from being a Noachide.
I’m pretty sure I’ve mentioned the five years I spent searching for the truth when I was around your age and having quite severe depression for a year or two. So I guess I see echoes of myself in what you write.
I personally believe in what you are doing and that if successful through the aid of a loving God, you will have a firm foundation which will enable you to navigate the years to come including family life. That path will enable you to overcome trauma and psychological injury from your upbringing.
All the best with that.
