READY TO QUIT

So, I've given my resume to hiring professionals and other professionals. I've haven't been able to land a job for 6 years. I've been told my resume is great, yet I'm over qualified. I can't even obtain a job in fast food or sales, like Wal-Mart or Target, things below what I earn now. I've been applying to everything everywhere! I'm how can I have a really good resume, but I'm not landing a job anywhere, I've even given my resume to people I don't even know to look over my resume and they don't even understand why I'm not being hired. I'm abour ready to give up. I have a job now, but there's no room for advancement. Wanted an additional job to be more stable, be able to go back and finish school, but I'm not having the best of luck right now 😔...6 years later and I'm still trying to find a full time job, so I'll be ok to leave my current job 😔
