Welcome!
I am glad you posted. You will find all kinds of support, wisdom, and kind folks here. There's been lots of great advice already in this thread. I just want to add that I really liked you "No more excuses, no more regrets" line. That's exactly how I felt! That sentence rocks!
I am still new to the sobriety game, so others might be able to offer perspectives from a different vantage point. All I can add is that in the relatively small amount of time I have been sober, I have had an exponentially increasing love for life and everything I do in it.
I wish you much luck and happiness. Welcome to SR!!
