My life is so out of control right now, what should I do?

So many things have happened in my life these past 2 years. I was happily engaged for 2 years, then broke up with my ex in March this year. I moved out of the state with my then fiance a year ago, but then had to move back home to my parents house. Because I left my good paying job, when I moved back I was fortunate to get my job back, but making only 10.75hr working 6 hrs mon-fri. Was in school for a certificate to become a pharmacy tech, but when I moved back I changed what I was going to school for, for a Graphic Design associates degree. Now my studies are slacking in that. I’m 27 yrs old and still live at home with my parents whom I don’t get along with at all. I’ve convinced myself I can’t afford to move out… or maybe I’m afraid of failing again. I don’t know, someone please tell me what I should do, I feel so lost.
