Very Sad!

I did not get the job!:-(( I am thinking about going to a college to get a degree in accounting or Sonography. Both needs 2 years to complete an associate degree. My background is medicine, so Sonography will be easier for me, but it is very hard to get in, even i pass every process, i still have to wait till the fall of 2010. I can start doing accounting right way. I am already in my middle of 30s and wondering if it is too old to start a new career. I stay home taking care of my family for too long, so it is very hard for me to find a job if i do not refresh myself. I feel that i will kill myself if i stay a little longer. Thank you for your advice!!
