Struggling with College Transition and Feeling Out of Place

hey, so idk what to expect by posting here but I feel like I need somewhere to vent and I think the community here seems really supportive, I’m hoping someone will understand. I am a third year in college and my semester just started up again. I have found that every semester I have a really hard time with the transition back into classes/living in a new living environment. I’ve had random roommates every year of college and this is no different. The thing is in past years, I’ve really gotten along with my roommates fast and they’ve become some of my best friends and like rocks for me. This makes the transition so much easier. But this semester, I am in an apartment with 4 singles and everyone seems very reserved and kept to themselves. I have tried to initiate conversation but it hasn’t been anything but friendly, as much as I think we could get along well. Because of this, I think my transition is so much harder than it has been in a while. Last semester I was on a different campus abroad and I had a really traumatic semester for a number of reasons but I at least felt secure and comfortable in the place i was studying. I never felt homesick and I didn’t need to be kept busy to feel okay. I can’t say the same for my college town, and its never felt okay. I have a lot of close friends here who I love but because of the nature of the college only half of them are ever here at a time. I also feel like I don’t have a strong friendship “group” at my school like everyone else seems to have. But even when I’ve had the most friends and been the happiest on this campus, I have not felt that security or that comfort. My homesickness gets really bad when I’m here and it propels my anxiety and depression onto another level. I talk to my therapist weekly and that definitely helps but her main suggestion is to take a break and some time off or drop out which just makes me more anxious. I only have about one semester of credits needed to graduate and I really want to do that for my own sake. Because then I can leave this town. I guess this wasn’t very coherent but I’m wondering if anyone else relates to feeling extremely out of place and immediately anxious in a particular environment. It is definitely very much an environmental thing that I feel like I don’t have the power to do anything about. As much as I see my friends etc, as soon as they leave I am left feeling absolutely crippled mentally. I have so much work to do and things I could be doing to keep me busy (much more than at home) but I find myself avoiding that and leaving myself with my thoughts which makes me spiral. It feels self-destructive in a way but it’s like I can’t help it. I don’t know. I feel like I’m just speaking into the void so I appreciate anyone who takes the time to read this. I guess I’m just wondering if anyone ever feels the same way about feeling really misplaced in a certain environment.
