Psychology is one of the most popular majors in spite of the fact there are few jobs for a person with a bachelor's degree in Psychology.
You can only realistically expect to make a living in this field if you get a PhD so you can set yourself up in private practice as a Psychologist. To do this you have to graduate from your bachelors program with a GPA of at least 3.0. If you think you can do this and commit yourself to at least 4 years of additional schooling after you get your bachelors, then great.
But if you do not think you will get at least a 3.0 or do not intend to stay in school past your bachelors degree then you should consider a different field. There are vastly more people with a bachelors degree in psychology than there is anything resembling enough jobs for them.
Since you need a PhD and once you have a PhD no one really cares where you got your bachelors, just go to the place you can go for the cheapest, generally your closest state university, as an in state student. A less competitive school is best as you will end up with a better GPA. A high GPA from a less competitive school is better than a mediocre GPA from a competitive school. Save your money for grad school and your PhD. It is normal to go to a different school for your grad degree and PhD anyway.
If you do not want to pursue a masters in Psychology, you can also go into a masters program in a lot of other areas or to law school as well.
People with only an undergrad degree in psychology and who actually got a job that had anything to do with the degree made a starting salary of $36,000 per year on average in 2009 according to:

Some people confuse this with psychiatry. To be a psychiatrist you need to become a medical doctor first and you first need to get into medical school which is even harder to do that getting into a graduate level psychology program. After getting your MD you then specialize in psychiatry.
