I feel like I'm a wrong person

I started college and it's been like 4 weeks. I'm 20 years old and I tried my best to make friends and I'm still trying. However, sometimes I feel unappreciated. I'm in a long-distance relationship, my boyfriend is 4 years older than me and he works. So we can't talk that much as before. And it makes me very sad because I feel lonely sometimes. And I feel like people would always like me as a second option. I made two friends in my class, but one of them has got covid and the other is just another world. I feel alone even when I make friends sometimes. And I also miss my boyfriend but lately, I just get mad at him for silly reasons. Also having more responsibilities makes me very stressed, mostly when I'm alone. I just want somebody next to me that understands me and makes me feel it. I know this is something I have to change in myself but it's hard for me. Anyway, I just wanted to share.
