Mom asked me to move in with her & dad a couple months ago & I agreed but can't move for another month. Since then every thing I mention of bringing with me (my own mattress/springs, TV, photo albums, bicycle,...) she gets upset & says I don't need to bring those because she has a TV & bed I can use & she doesn't want to look at old photos!
They have a four bedroom house & she has designated one bedroom & one of their three bathrms for me to use. She also does not want me to put anything in their garage, attic, or any other rooms. I currently live alone in a three bedroom house.
I suggest you and your siblings get together and arrange for some paid outside help for your parents. Whatever you do, don't consider throwing your life away by going ahead with this.
This is the time that you sit down and have a serious discussion about how long you are staying, how much care you are willing to give (are you up for bathing, toileting, diaper changes...), and how you will be compensated for what you are giving up.
I strongly recommend you set up a caregiving contract and be paid, make allowances for pay increases as their needs increase. At the same time make sure their POAs are complete and that you are all on the same page about life extending procedures.
You might think all of that is overkill, but too many of us have jumped in to help our parents temporarily and find ourselves still there years later struggling with their care needs and facing a future of poverty. One thing is certain, they will get older and their health will decline. And any estate that you may be counting on may need to be used up for their needs, or become the bone of contention that tears apart the remaining family.
