Am i forced to take pills? What can i do??

So i’m 18 and i take pills for depression and anxiety my medication is called wellburtin 300 mg something like that and i’ve been taking some adhd pills amphetamine dextro combo 20mg and i told my doctor how i don’t feel like its working because i still can’t focus etc so she put the dose to 30 and i started feeling bad at work i barely want to eat and i threw up 3 times already. I’m so tired of being on these drugs on top of that i take birth control pills and that gets me bitchy af. What can i do? I know diet and exercise helps but i can’t even eat healthy foods at my house at all. I don’t know what to do because it feels like i’m forced to take the pills because for example the anti depressants if i stop taking them i start getting even more depressed please help me
