I DO want things to improve and I agree that we need "a do-over".
---> You CAN'T do a 'do-over'. Once something is done, you can't unspill, unsay, unwreck, uncut, unglue and so on a so forth. And while you can 'undo' a seam you have just sewed or a a few rows that you knitted or crocheted...the fabric, the yarn, the thread...it's not the same, it's already been changed by your actions.
---> What you CAN do...is move forward. And hopefully, with a favorable outcome, but there is no guarantee. And it a constant work in progress until that progress becomes habit and that progress can take time. It takes just seconds to wreck a vehicle, but how many hours...days...weeks does it take to repair it? And then...it may be 'AS GOOD as new', but it's still not 'new'.
If you air your dirty linen in public, expect people to comment on the skid marks!
