You are correct - you will not be able to be licensed as a nurse with your felony. You can pretty much rule out anything that requires certain types of licensure and care of vulnerable populations, and also rule out anything that requires handling money, due to the nature of your felony.
As you already know, a lot of employers aren't going to want to hire you, period. They just won't take that risk. Where I've seen people with felonies do well is either in running their own business, or working in a field that has such high demand for people with X skill, that they'll be willing to overlook your felony, such as computer science. Another option is to find a job with a company that's hired other felons - so for that, you'd need to talk to your resources in this area. You might have success if you try to get a job with a small, local business (a mom and pop) where you know the people there. Generally, small, local businesses where you are known may be more willing to take a risk on you than big chains.
What I might suggest is that you think about what you're good at, and what you like to do, with the goal of perhaps opening your own business (that does not involve licensure and exposure to vulnerable populations - so not a daycare, for example) in that field. As part of all of this, find out what education is needed to go into those fields, and then take your first steps.
ETA: the first poster is not correct. You can qualify for financial aid with a felony. Many of my students over the years have been felons with financial aid to help them pay for school. It's only if you had a drug conviction while receiving financial aid that you'd be ineligible.
