Depressed & stressed out girl. I feel like im doing nothing with my life. Help?

You feel your life is going nowhere. What will change if you stay in Sacramento? You need to be on your own and experience a change. Take the job in San Francisco and establish a new life with more opportunities. Sure you may initially miss your boyfriend, but there are many other people to meet and things to do in SF, which is more metropolitan. Give it a chance. You're young and got nothing to lose. Think of it as a new adventure, which could be life-changing.
