tryhard,
Hashem wanted you to fall! Yes, believe it or not, it was hashem's will!
Everything in the past was Hashem's decree. You can only control the present. Your Bechira is NOW.
So, focus on NOW. Right this moment. And then another moment. Don't spend too much time thinking "I fell today" or even "I've been going strong for 3 weeks".
Your LIFE is occurring in the NOW. Who you are now is not who you were yesterday. It's not who you will be tomorrow. You are who you are right now. So right now, choose which direction you want. You already said in your post that you are scared of the Yomim Noraim. So you are choosing the path of good. Excellent. Continue on that path, take one moment at a time, call out to Hashem when you feel it's too much. He'll help you. Just forget the past. DO NOT THINK ABOUT YOUR FALL. After all, what's the difference between this last fall and the one before it? It's just that this one is fresher in your memory. So tell your mind to shut up. You don't care about the past because that has nothing to do with your life which is NOW.
I love you like a brother,
Levi/KH
