I hate studying: major procrastination and inability to focus

my school’s mid years are next week. i’m a jc2 student who repeated jc1 so the stress to do well for As is there. i spent the whole hols not doing anything productive even though im already so behind on school work. i just tried to sit down and do a math timed practice paper and i couldn’t even concentrate for an hour before i picked up my phone and entered youtube… watched a bunch of adhd videos not sure if i should go see a psychiatrist to see whether i have adhd (just for ease of mind maybe) or whether im just being a lazy procrastinating student :sob::sob: i really was determined to finish the paper in 3h but i reached a qn i was unable to do (after skipping multiple qns i cldnt do) and gave up… idk what to do already i think im gonna fail my mid years :sob::sob:
