My only *advice* is try to be careful about being what you think your husband and son need you to be (sorry, I can't remember how old your son is, so maybe ignore that if he's on the younger side.) My own experience has taught me that if I am being the best version of myself FOR myself, then everyone else benefits residually, especially my husband and kids. I've been rushing around a lot less lately and suddenly my toddler has an easier time listening to me when I give her an instruction. Not rushing around makes me feel so much less stressed too.
I think it's so cool that you have a sponsor who is also a counselor! That's a pretty good 2 for 1 deal.
