Hello Self!
Solipsists are always alone but schizos are never alone; so best pick up your best bet for the correct shade of grey between those two for any given situation. Except if you're actually one of those mystically inclined people that are in some cultures labelled schizophenics, and even of them if you're of the particular subtype who think they're GOD or something. That can of course sometimes have it's own illusory solipsistic aspect. So don't do anything that the I in you wouldn't do. Luckily or not that one's pretty easy to accomplish.
