Dealing with a high strung mom?

Your mother needs to see a counselor. I'm not a pschycologist, but she sounds just like my step mother who is paranoid schizophrenic. Medication can help, but the person must be willing to seek professional help. They need counseling and to have their medications monitored by a professional, because it sometimes takes several tries before the right medication is found. If they are not willing to get help, there's nothing you can do but be patient until you are old enough to move out of the house.
