college tips!

hey guys, I’m currently a senior in high school and I’m looking for tips on applying to scholarships and just any tips you guys wish you would have known before starting college! I currently go to a very small Christian private school in Mississippi, and I plan to attend a community college. I plan to study health sciences but I’m not sure exactly what major yet. I’m thinking between radiologic technology, medical laboratory technology, sonography, or health information technology/management. Anyone who went to college for one of these let me know your experience and what you now do for work! I’m most likely either going to get valedictorian or salutatorian at graduation and I’ve always had very good grades. Sonography was my first choice, but I would have to get farther from home for that so now I’m thinking either radiology or medical lab. i have anxiety and i don’t believe i could handle a large university, especially somewhere that I don’t know anyone. Anyone from mississippi, give me your experiences and recommendations!
