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'.
