I will concur that you should likely get a different bike. You are setup semi-upright now. It may not be possible to get the bars much higher. You could find bars with more rise. Maybe switch the stem. But you aren't going to get much further up the. You have now. That bike is pretty "racy."
Maybe keep that one as is and try out something like the Linus Dutchie or a Public C7. These are very upright and not semi-upright like you have now.
