How do I change this?

I started dating probably my freshman year of college. I dabbled a little with texting in high school but overall not much. I feel like I never get into depth with guys. It’s like we flirt all day but we never talk about anything serious. I don’t feel anyone truly knows me of that I truly knw the person of interest. I don’t like to seem nosy or invade personal business I just thought it should be something that happened naturally but I don't know. It’s weird. I want to be able to finally connect with someone. I don’t feel I’ve ever been loved or been in love myself. I just get super attached. Why can’t I form connections? I also have this problem with making friends. I don’t know how to do it. I am quiet but I really want to meet people. It’s unfair. I try to socialize now that I’m older but I always feel so awkward after. I want to meet new people, including love interests and friends. I’m supposed to be graduating soon and I fear I’ll be alone eventually. Even my friends now don’t really know me. They tell me how I feel about things or try to tell me what I need to do or want to do. I don’t like it. What do I do?
