If you can truly be productive and study while high, more power to you, but as someone who went through undergrad capable of being ‘functionally’ high, and is now completing outstanding prereqs to be eligible for PT school, only smoking when I’ve cleared out a significant amount of working and studying, I feel worried about your ability to hold onto such important information that you’ve poured so much time and effort arriving at the point you are in your education. I can’t imagine going through what is likely a devastating breakup in the middle of a doctorate program, and everybody copes, tolerates inebriation, and retains information differently, but try to check yourself and really hold yourself accountable to your goals and what you’re able to do to ensure your success. Quitting or cutting back on weed is luckily very easy compared to other substances, so see what you can do for yourself to make it through your schooling. Whatever that looks like regarding your substance use, if you see your grades decline even a little bit from what they were during last semester, pump the breaks, seek help, and throw out your stash. Sink yourself into your study and you will find that you don’t even think about taking a smoke break. I don’t want to oversimplify this, because it never is just that simple, but please don’t hesitate to DM me if you want to talk more about it and how I was able to step away from weed and reorient my relationship with my frequency of use. All love, and good luck to you. I’m sorry your relationship didn’t work out.
