It takes a while Noam. It is great you are sober but this is far from the best you are going to feel. More sober time really quiets your mind and your thoughts and allows you to identify old resentments as nothing more than that, and then you can leave that in the past. It is a key to recovery and I worked on that every day for many months. That calm in your noggin too allows to think about contentment, humility and gratitude - another few keys to an ongoing recovery in my humble opinion. Hang in there Noam, you are doing great.
