Glad to hear things are going well today Kat. Having a plan for life in general really helps, and especially for the initial stages of getting sober.
I get the shame/regrets too - that's totally normal to feel it for things we've done in the past. But the solution is of course not to dwell on it because you cannot change any of it. You CAN make choices today though that will show others that you are serious about recovery and improving your life - and I can guarantee that in the long run, most people will remember that more than the bad stuff.
