Trying to work again - it is so hard!

I have been trying to get back to work for a decade now... started my own business 2 years ago. I was told I would never work again and so it was a huge thing to even try. Ughhh I did things wrong and now realize that I would have been financially better off to not even try. It is so discouraging. I will keep going because that is just how I am but gosh, this is the hardest thing to try...
