Brother, try your best to go out, is there anyone you can spend time with? Friends or maybe relative?
Trust me, staying locked up in your room is not healthy. You will lose interest in the outside world (which you stated you already have) not to mention social anxiety is no fun, it will take over your life. Try to get out and walk to a park or something, but don't do it alone, do it with someone else, it will make a big difference.
Other than that, praying, making dua alone is nice. Make dua that Allah make it easy for you and also that he increases the iman, health and well being of your family. Make this prayer especially during azan or when it is raining as this is the time when duas are not rejected. InshAllah, I will keep you in my duas.
