Florence, You are going through a lot right now. Maybe to give yourself a break from the added stress of your parents watching the kids you can look into discounted or free daycare programs your county or the state offers. I found out that my youngest could go to State Preschool for free even when my husband and I were just seperated and not even filed for divorce or seperation yet. Check online and ask a lot of questions. There is more help out there than I had ever heard of.......
If you can aliviate so of the other stesses in your life maybe you will be able so see some of the other more pressing issues a little more clearly.
Take care,
