I think your dad was just showing his concern as in that he doesn't want you to need medication. On the other hand, it was totally insensitive to say that.

It's like telling someone with diabetes "I hope you get to a point where you don't need insulin any more." Diabetes is a progressive disease. It progresses faster for some and slower for others. But, in the end, the pancreas eventually can't keep up and even type 2 patients need insulin. That doesn't mean they failed or are bad people. It's just part of the illness. People don't understand this and then feel huge guilt over not being good enough to overcome or cure their diabetes. They cling to the false hope that things will reverse, and it's not common for that to happen.

It's just the same thing for us. (I actually believe diabetes and bipolar are extremely similar except for us it's a brain thing instead of a pancreas thing, and no one has figured out our insulin yet....)

Don't hate yourself. You are beautiful and wonderful. If you need meds, then you need meds! Oh well! That doesn't make you a failure or less of you. Instead think: "I will attain wellness," and if that wellness includes meds, that's totally fine. If it doesn't include meds, that's totally fine.

I think, though, maybe have a talk with your dad when both of you are calm and tell him what he said really hurt you. I mean, it sounds like he loves you and cares, so I think he'll listen.
