Unfortunately, Eden, psychosis is an illness where it's hard for the person who is experiencing it to see they are sick. Meds aren't bad it's what got you "unstuck" from spirit world last time. Just remember, whether you tell them now or your team figures it out later, they have said they will hospitalize you again. So, while meds may be a choice now, I presume they'll do much the same thing as last time in the hospital where if you refuse they'll get a court order for them to administer meds. Ultimately, going along with treatment(ie: taking meds) seems the "easier" way in this case.
