Returning to the workforce

So after 3 years of not working, I'm finally going to try and get out into the work force again. I'm a right leg above the knee amputee. The job search isn't going to be easy. I feel like I will be discriminated against because of my disability and I'm not sure how I feel about that. But I will not get anywhere if  I don't try so here I am trying. Praying all goes well.
