i deal with that urge everyday az, i totally understand. Please know that slipping a little bit doesn't completely undo all the progress youv'e made. Cutting is an addiciton like anything else, sometimes we fall of the wagon. It's ok. You recognizing that youv'e slipped and wanting to get back on track are sooo important. You seem to have a strong support system- use them.
Also, soemthing that iv'e found to be helpful in my "cutting sobriety" is to do things for myself, little tokens. You know how AA has those coins? 1 day sober, 30 days sober, etc? something like that. Something i can look at and say, look what i did. sometimes it helps put my anxiety into prospective.
It's not always easy, but you can get through it.
