Is it normal to want to be homeless?

So basically, I am a Marine vet. I did my four years, and now when I left, I went back home to my family's. I already had a job lined up for me, my friend's parents own the business and got me hooked up, so I had a job as a warehouse man kicking boxes and stuff. Then a month later, the managers told me that they do not support the military, or veterans, so they terminated my employment. So I brushed it off and just tried to get back on my feet and find somewhere to work. Eventually my family didn't like how I wasn't working, so they kicked me out. I had nowhere to go, so I went to live with my fiance and her parents. They have been good to me, they treat me as if I already am a member of the family. I'm living with them to this day and I am still struggling to find work. I have sent resume after resume, application after application, left and right, and I have yet to hear a phone call or message or anything. I feel that it will get to the point where they wanna kick me out too. So if I can't find work, I might as well call myself homeless right now. Because that's how I'm gonna view myself. People who have steady careers or a steady job would never understand this, unless they got laid off or fired! What can I do!?
