I love my cat too! Having a pet is so comforting. She drives me crazy with all the attention she needs, but she's worth it! Can you have a pet where you live?
Have you tried going out to meet some people, make some new friends? Have them over for dinner one night!
When I went to school in another province (I'm in Canada), I found that I got lonely too. Until I started having my class mates over for visits. That really helped a lot!
