Wow, that is a good GPA. I don't know what to tell you. Obviously it is pretty tough to get into a pharm school, so if I was guaranteed in somewhere then I would probably stick with it.
What is really important is the reasons you have for wanting to leave. If you don't think the situation will change and you will always be unhappy, then it may be worth the risk.
Definitely get some pharmacy experience. That will count a lot. If you decide to leave, then just work on making yourself a well-rounded applicant. The fact that you have a bachelor's won't stick out if you have a lot of other things going for you.
Good luck!!
