Is is possible for you to go see a therapist for some help? It sounds like you have some unresolved issues with your mom's death and that it makes you have nightmares. I know that is really hard to cope with because I've had issues with sleep myself and with past trauma.

Would your doctor let you take something like ambien at night to see if it will help you? The fact is you do need some sleep and if you only took one mg klono at night and did not increase the dosage there's no reason you could not use it sometimes. If you had a therapist you could see about the underlying issues you may be able to resolve the grief or fear or whatever is disrupting your sleep and it would be much better for you in the long run.

You need to take care of yourself so you can take care of and enjoy your children. You matter.
