Don't get too down on yourself. It took me 7 years to finish a 4 year degree. Sometimes you just need a break. I dropped out halfway through semesters twice. The first time was fall semester and I took spring off and started again the following year. The second I was within two months of graduating and ended up taking the rest of that semester, a full year after, and fall semester off before going back in January and finally finishing in May. There's nothing saying you can't go back and finish once you're ready or that not finishing makes you any less in any way.
