My advice is to NOT leave your kids. That would devastate them and would harm them for the rest of their lives. You had and bore children. You owe it now to them to stick it out, to love them and care for them. Even as adults, kids still may need their parents. I am nearly 50 and still ask my parents for advice now and again. You decided to have children; therefore, this is now your obligation to be their mother. Do not abandon them. That would be horrible. Just think of what it would have done to YOU, had YOU been abandoned as a child. It's a most selfish thing to do.
