For context, I'm 22 and in Canada. I was prescribed Zoloft when I was 19 after years of therapy failing me. I feel much better when I'm on them, sure I break down every now and then but they're not strong and most of the "depression" part of it is gone. Most of my episodes are of anger and I'm trying to work on them but when I miss my medication, the difference in motivation is highly noticeable.  
Today, in a bpd fit, I threw my medications out in anger. My dad came in and said he was proud of me because it was likely my own physchiatrist failing me and making me an addict. I regained my braincells for a second and second guessed myself like "wait, throwing these out are probably a bad idea, they have been helping me so much and bpd is far less severe and I even just recently managed to be off suicide watch thanks to them helping me" but my dad kept saying I sounded just like a drug addict. So now, I'm confused. Has my own psych lied to me?? I'm probably still in my episode and my dad isn't against me taking them, maybe he feels like i already got better so i dont need them, even though they are the reason I'm better? Like he's diabetic, its kind of like topping up on insulin. It doesnt even get me high or anything, I just feel like normal person??? Am I addicted?? Have I been lied to??? Should I actually quit them??? Please help????
