Marin I understand you are upset about not seeing your grandchildren. However I think the most concerning thing is whether your grandchildren are safe. You mention mental health issues and neglect. The parents mock you and are abusive to you. How are they I wonder with the kids?
If social services are not involved in anyway then I think you should contact them ....or ring the NSPCC for urgent advice.
What colours remind you of your childhood home?
