Hello, My Boyfriend Of Almost Ten Years Is Schizophrenia And

Hello, my boyfriend of almost ten years is schizophrenia and I believe bi-piolar and I was wondering if I should just give up now because its making me insane to deal with his illness because I don't know what or understand how to treat or talk to him when he's like this, but when he's not having an episode he's a sweetheart and I've grown to love him because deep down I know that's not the person that I feel in love with
