First of all, I hope the Latuda works well for you. It certainly has for me. I am on Latuda and Lithium.....and am the most stable I think I have ever been. The Latuda makes me "just be able to do things" like you mentioned.
Secondly, I am so sorry for the health issues your daughter and mother face. I know it is all stressful for you. You are in my thoughts.
