I would get more practice leaving the house, being around other people. You cannot learn to be social without being around people and observing what they say and do and giving it a try yourself. Ask your mother for some chores to help around the house. Go to the grocery store, maybe take a continuing education class at the local community college or community center. Join a group at the library or your local hospital (depression, anxiety, etc., check what support groups they have that you think might be useful to you). Your local library probably has a lot of information on what is locally available to you.
