Seeking a little help

I went away to a school that is outstanding in what I thought would be my desired major. I also went through recruitment and pledged Theta. I love my sorority, but am having second thoughts about my major and likely will return to Oregon next year where I only would have to pay in-state tuition. At my current school it is almost impossible to transfer and live in the house. Could you tell me if transferring and living in is a thing at Oregon? Also are Thetas known to be a welcoming house? Can you tell I'm really confused right now? Thanks for any advice you can give.
