I am having a hard time standing, sitting, walking,. I also fall a lot.

Hello Anon
Thank you for writing.
Your symptoms are very broad - there could be many reasons for this, including vertigo, or other ear condition - or a nerve or spine issue.
When you say you can't sit or stand, are you lying down all the time? Do you feel weak or in pain? When you fall , do you lose balance and stagger or simply collapse?
How old are you? Do you have other health conditions?
We need more information from you to help you further.
Best,
Susan
