I really like your username.
I am also pretty tethered to my bedroom and my computer, though I've summed this up to me being too much of an introvert to enjoy being surrounded by a large number of people on a regular basis.
If you feel it increasingly difficult to leave the house, then it may be advisable to be sure that you are not developing depression or a social phobia. Bullying and being exiled can lead to both of these things.
