Is 300 too much for me?

I have ADHD and mild depression and anxiety. I started taking 150mg of Wellbutrin 3 months ago. My depression and anxiety felt much better but my ADHD symptoms didn’t improve much. My doctor increased my dose to 300mg about 3 weeks ago. I am having a increase in crying spells and some additional anxiety. It has greatly helped with binge eating issues and has helped somewhat with energy and focus. Have I not given the 300mg enough time to work? I don’t want to go back to 150 but worried it is making my depression worse. Should I stick it out a few more weeks?
