I'd say I'm sorry to hear about your difficulties but in the end this may prove to be the best for you so rather I will merely wish you the best of luck.

In that respect I am going to offer you a little advice from the perspective of a boy-made-man who's mother was a single mother who divorced an abusive, psychotic husband and raised 3 underappreciative (at the time) kids. She worked 4 jobs some days just to be able to provide for us.

1) Believe it or not, your kids will respect you for your strength. They may even (as I did) tell you directly in 10-15 years.

2) Life will be very - very - VERY hard. Do not give up but at the same time you will need some 'you' time.

3) Your kids will be extremely difficult and frustrating. Sure, this is probably normal but they will be even worse. No, it's not intentional, and no there's not much you can do about it. Just try to remember murder is still illegal, ok?

4) Believe it or not, kids do get tired of cheesy mac and hotdogs. Go with other cheap foods from time to time such as grilled cheese, pancakes (for dinner yay!) or spaghetti.

Good luck and keep your head above water.
