I lost my job today....

So I lost my job today because I was sick/tardy more than 10 times over the course of me working there. I loved my job, it was in the medical field and it was what I wanted to do with my life. It is completely my fault for either not taking better care of my health, not anticipating traffic or driving times, not double checking what time I worked, or that one time when I overslept. I have always been a little more of a tardy person, but I work on it!! I've been trying really hard and leave 15 minutes before my shift would start. I was one of the most experienced people at my old job and I was let go today as of about an hour ago. I miss my job and I'm not sure what to do next. I'm 20 years old and my boyfriend suggested we move to Florida - from the mid west - where one of his friends owns a restaurant that we could work at and live down there. I do want to leave the mid west, but I'm skeptical to move. We've been together over a year but we've had our share of problems. What should I do? Start over here in Iowa with a new course of life? Or leave and move to Florida with my bf and work in a Mexican restaurant? The restaurant is very successful and my bf's best friend just moved down there in September to do the same thing my bf wants to do now.
