i feel so useless because i cant find a job anywhere

The after school program I normally work at hasn’t given me much work at their summer camps. I’m looking for another job to sustain myself while I also work as a freelance copywriter and pursue my true passion of writing. I’m looking everywhere for full time copywriting jobs but nobody seems to want me. I feel bad because my dad sent me this retail job which I don’t want. However it is not because I think retail is beneath me but the fact that it does not pay well at all. My dad was trying to help and I really appreciate that but the thing is I am 35 years old. I still live at home with my parents and I desperately want to move out and get my own life. That is why I am looking for a more full-time job that will allow me to live that life. I’m not looking for an extravagant luxurious life. I just want something that makes me happy. Retail will not allow me to live that life. It will not allow me to live independently. How can I get people to notice me and find a job that will allow me to live the life that I want to live. If I have to go back to working as a paraprofessional then so be it. Heck, I would even be fine with working as a receptionist both those jobs would definitely pay more than retail. I keep looking and looking, but I always come up dry what does it take? Am I really not good enough for anything? Sometimes I feel like the only thing I’ll ever be good enough for is lying on my back.
