Future Apartment living only option after parents are "gone"

So last night, I accidently got one of my answers to a question from my script for next month's talk.  There's a lot of stuff to cover here.  But let's get  some of this out  -  group homes seem to be out due to wait lists,  and because of cost of property taxes, water, and Electricity,  staying in the house isn't an option trust or not.   So it seem like an apartment is my only option if Mom and i don't move out if  my Dad predeceases Mom  after my parents are "gone"  

This is  problem in my opinion because unlike the parents and my sister both of them have pre-existing experience in living in dorms and apartments  at the moment I only have the former due to Disabled Summer Camp  last summer.   If I'm last one here- having to move out of the only home I know a 3 bedroom house to  a one bedroom apartment is a huge and scary thought.  That doesn't  include my parents don't understand most apartments here require  additional money for hydro and water.   Since  unlike Luna's apartment   Hydro, internet and sometimes water  is "extra" money and isn't included in most apartments.    I have checked apartments for years because of thoughts of wanting to move out.

My parents want me to be able to get a "decent" apartment when they're gone.  But that causes me another problem -swimming in the summer  due to an ear tube in one of my ears means I can't go in the deep end of in-ground swimming pool.  So that means I'm stuck at the shallow end of a pool and  that means I can't do big circles like I could in the summer  in the family's backyard above-ground swimming pool like going 100 times over and over in the pool.   trying to do an oval in a smaller space (shallow end) isn't the same thing as  big swimming pool that's above-ground.   

With what I know about apartments, and that's not much,  but if an an apartment had a swimming pool,  it would likely be an in-ground one.   It's not like I, as newcomer could ask for them to make an above ground pool just for myself right?

The main problem is having to uproot myself from a 3bedroom house to a 1bd apartment if Mom and I don't move out if Dad dies before  Mom when i never moved in my life.   I lived here for almost 36 years (will be 36 in June).  The dorm experience from Disabled summer camp barley counts when the dorm is barley an apartment no stove and only a mini fridge.   Also it's a 2 person dorm room.
