how the f do i get more motivated

I’m 18 (f) and just graduated high school. i’m halfway into my freshman year of college and i’ve never been less motivated. i’ve been diagnosed with adhd for 9 years now and have been on a variety of medications, but my current is azstarys. i used to have the regular bursts of energy but they used to last significantly longer. i would have a high for like 2 weeks and my crash/recharge would be for the next two of the month. lately it feels as if my high is like one week every two months. i’m extremely ambitious and when i find something i want to do, ill also get that same burst of energy and make powerpoints, scrapbooks, literally anything to plan out my way to success and then i never go through with it. how do i fix this. it drives me insane being genuinely motivated rarely ever when i KNOW i have the potential to be so successful and i just can’t push myself. for college i also opted to do one year of community college to finish my associates degree as i already had half the amount needed, then to transfer elsewhere to get my masters in business management. however, i find it SO rare to find the motivation to get my work done. im doing online and it grants me the time i need to get assignments done, but i find myself STILL abusing that opportunity and ill have a day where ill get half a module done and then set it aside for three more weeks. please help with your guys’ experiences, im going insane
