First off, good for you for taking control of your own life and getting help with your own issues. The only one we have complete control over is ourselves so kudos for you for taking back the one person you can direct.
Second, you need to stop thinking about her and accept that she wants to cut you out of her life. You are still trying to control her and trying to force her to hear you and she's taken back her own power by making it so you can't. Accept that and keep working on being the best man that you can be so that a nice woman you meet in the future won't have to block and delete you as well. In time and with your own self worth being topped up, you'll not worry so much whether or not she forgives you. She knows you're sorry now let it go.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
