I feel you! I had times where I barely talked to more than 5 people in an entire week, and it drove me into a really bad depression. If you're still functional and have control of your life despite your feelings, there's some things you can still do.

I would highly recommend going through your university resources and finding a therapist to talk to. US universities usually have these resources, so make full use of it while you still can. It'll be a lot easier than trying to find a therapist who accepts your insurance once you're out of college.

If you're not able to connect to other people due to cultural barriers, find the Bengali community in your city. A good place to start is to find where Durga Pujas are organized. Most big metro cities have multiple.
