Here are some Ideas I came up with
1. Get a pet
Pets can be great company and if you get a trained one they shouldn't be that hard to take care of. You can also benifit since hte pet will help you get out more.
2. Start those piano lessons
Its never to late to learn something new. Plus maybe you'll have fun.
3. Join a club with fellow people that have the same issues that you do.
Being around people that can relate to your problem is a big help. Plus you might make some new friends
Hope this helps!
