Lamictal was excellent for me; there are other relatively new medications that are helpful for many.

Ask your doctor about a food med called Deplin. It's very inexpensive and helpful, especially for people who cannot manufacture the stomach enzymes that make folic acid (vitamin B9) available to the brain. 20 mg. per day helps me remain calm and have a
good feeling tone. It's inexpensive in terms of medication costs. I wouldn't be without it.

Take care of yourself and ask for better care for you. Let your doctor know that you
know that lithium is one of the most toxic medications out there and that you don't
want to risk damage to your kidneys by continuing to take it.
