I feel like I don't belong....

I got pregnant during my senior year of highschool and had my son during my freshman year of college. It's honestly been hard. The looks I got from people when they would see me heavily pregnant walking to my classes. Me and my boyfriend go to the same university and after our son was born during the spring semester they were able to move us into family housing. I'm honestly just really depressed because I don't feel like I belong at college. If you think the looks were bad when I was pregnant, the looks when I bring my son there class is terrible. I usually only have one class I need to bring him too. Other classes my boyfriend isn't in class and he will take our son and vice versa. Well the one class HE has to take our son to was having an exam so he needed me to take him with me to my regular class. I did and I sat in the very back. He started crying in class so I breastfed him back there to keep him from crying. I was completely covered. He was fine and stayed quiet the rest of class. As I was leaving I heard some other girls talking loudly about how I should just quit college and how disgusting I am for breastfeeding him in class. Even though i was in the very back. They had to turn their heads to look at me. And I had on a cover. I just don't belong here. My boyfriend brought back some food they were giving out in the main dorms but I just don't feel like eating.... We go to stay with my boyfriend's brother during the summer and I'm honestly thinking about just not coming back....
