My dad wants to stop my stutter. I don’t.

My dad wants to stop my stutter. I don’t. I’ve had a stutter since i was 6. I’m now verging on 18. I’ve been with it for my whole life and as much as it sucks at times, it’s shaped me into the person that I am today. It’s taught me resilience, perseverance, and so much more than anything else ever could have. However as of recently, My dad is obsessed with putting me on meds to try to help fix it but I don’t want it gone because of what it’s done for me. But he insists that it needs to be treated and fixed. I don’t understand why it’s such a big deal to him now and it wasn’t 12 years ago when it first started. And it hurts that he wants to get rid of a part of me. But no matter what I tell him about how I feel about it, nothing changes. He also has put me down about it recently as well by saying that a therapists patients won’t understand their words through their stutter and if i want to make it into the field that i want to, something has to be done about it. (For background, I’m going to college for psychology intending to be a therapist). I don’t know what to do because when I share my feelings with him he gets mad and says that I need to accept help and when I tell my mom about what’s happening, he manipulates the situation and gets her to believe him and calls me disrespectful. Any advice?
