Is it possibly your perception or your insecurities that make it seem like things aren't going well? What if you asked your roommates if you can join them the next time they watch tv or sit around talking or go out? It will take a few times to feel comfortable. If you continue feeling rejected or awkward, ask for feedback from the ones you've tried to connect with.

In the meantime setting up a routine or schedule for yourself can keep you out of bed. Set goals for yourself and add things you find fulfilling and build them into your routine. You have time to work on being the best version of yourself you can be. I'm not saying it will be easy...I have social anxiety so I know it's tough but it's worth it.

Best wishes.
