Yep, i understand - but you cant take it back or change it can you, so you will just beat yourself up and do more harm than good iykwim.

If you feel guilty, try to quit at a time that is right for you, not because you have too. Thats why you have probably failed. use your children as encourangement not the reason you have to quit as it probably isnt the right one for you.

Take care of yourself and try not to worry
