he shouldn't put you in that position if he cares about you... its difficult dealing with adhd and alot of people dont understand it, much less now with all the media and folks abusing stimulants.. everyone thinks that people with adhd are just trying to get high or something... im sorry you are in this predicament..
does he love you? if he does i would try to educate him about adhd and how it negatively affects you... if he cant understand that its really hard living with adhd, for some people atleast, then i dont know what your best option would be... some people are able to cope with adhd and compensate well, some people are more disabled by it... personally i cant remember anything, people look at me like something is wrong with me but when i try to explain i become a junkie..

i hope that you can educate him on adhd and how the use of medication helps patients with adhd, rather then him just thinking you are taking it to get high like so many people seem to think now..
