My mom told me that my sisters pdoc said her A1C levels are too high so he took her off her latuda and put her on lamictal

I'm upset because my sister is also schizophrenic and lamictal is NOT going to prevent her psychotic symptoms. So I'm just waiting for the inevitable to happen now .

Also I have a pain in my chest where my heart is located. But I dont care If its serious cuz I dont even wanna live any more any way.
