I do not understand how people fake this to get meds

I just got diagnosed or whatever and got 10mg vyvanse. This was after going to one appointment, doing sheets, and then going back. It’s only for a short and I have to watch my heart so it doesn’t explode or something like and do a bunch of tests and then go back😭😭😭 Idk if I care that much to actually go back but I know I should cus it effects my life immensely. Oh and btw the 10mg hasn’t done ANYTHING and I hate and have a fear of doctors so this whole thing is painful. I know if I go back and say this isn’t doing anything I’ll have to go back in another little while to check on it again if it goes higher. If I didn’t absolutely feel like I had to I really wouldn’t and honestly even though I do I don’t want to.
