I have a friend that I was dating that moved out to Chicago from LA.
She struggled big time... probably still is. She would call me every other weekend saying how alone she was and how it sucks, etc, etc.
It depends on you really. I would do my best to go out, try and meet people whereas my friend was afraid...
Generally, I think its hard to adapt to an environment you are not familiar with. It would take time to adjust and meet people. Depending on your personality and goals, that time can either be shorten or stretched....
