In 2011 my father died and my mother came to live with me because she couldn't live by herself. However, she refused to sell her home so, I had to take care of her house and bills, and she lived in my house for free. In 2016 we finally sold her house. In 2018, I found a nice independent living place for her. I would run all her errands and ended up paying for her groceries, medications etc... In 2020, her dementia got so bad that she was not able to stay there anymore. So, I had to quit my job and take her into my home again. With the COVID situation I did not want anyone coming into my home so, I also became her caregiver. I am by no means a rich person and I am feeling cheated.
You say that in 2020 you took her into your home because you were "forced to". No one is forced to take anyone into their home.
You quit your job and are caring for your Mother. Do you have a care contract agreement with her?Are you her POA? You should not be spending your money on your Mom. What are her assets. Are the assets from the sale of the home now gone? Does she get Social Security?
See an Elder Law Attorney to examine what Mom's situation is. See about setting up a care agreement with her if she is competent to do this and agrees.
If you are spending your assets, and you are using your own assets to care for your Mom and giving up your own job so that you are jobless and losing your job history you may end up broke, destitute, and without a job history. We have seen that before.
None of us here can know what your own and your Mom's assets are, nor what your Mom's mentation is, nor even if you are her POA or her guardian. More information on the facts in your case may help us help you with some answers.
But you can also see an elder law attorney for a few hours of time and work out how to work all this out.
If Mom needs placement so that you can work to support yourself, then she should do that, spend down her assets by paying for her care, then apply for medicaid to care for her while you work and save for your OWN aging care.
If this is done it must be in compliance with laws in your state. Taxes, etc just be withheld and you would have to file.income tax each year reporting the income.
