Adjusting to University as a Transfer from a Community College

Hey, I honestly need some advice because I know things need to change soon, and I desperately need help. If anyone has gone through a similar experience please give advice on what I should do. I recently transferred from a community college to a private Christian university as a junior and pre-med major. The classes are so much more difficult compared to the community college I transferred from, which has made me feel so overwhelmed and anxious. This is also my first time living away from home. My hometown is around an hour and a half to two hours away, so I’ve been going home on the weekends. However, I just feel extremely homesick since my mom and I are so close. It has only been us for most of my life so we have a super close relationship. Everything has taken such an overwhelming mental and emotional strain on me because I’m so worried about my grades as a pre-med major but on the other hand I’m so depressed being away from home. Is there anything I can do to make this transition easier because I don’t want to give up on this phenomenal university and my dream to become a doctor. Thank you for your time.
