Hmm. It's a difficult thing. I guess it's more of a "try it and see" sort of thing? Ask your psychologist to do the weening veeeerrrry slowly so hopefully your body won't even notice and it's slow enough so the lessening of effects aren't as noticeable? If you notice a big change then let your psychologist and parents know that it isn't working out and stay on it for a while longer

It's definitely not a bad thing to ween yourself off medication and I definitely understand wanting to be off of them. I guess just don't let fear stop you from hoping that it'll go well.
Best of luck! Let us know how it goes!
