Wildsmonica14,
Do you believe in a higher power (God or whatever your belief is)? I get lonely sometimes too, but I know that I am not alone...I see footprints in the sand.
Going to school and finding out who you are and where you fit into the bigger picture will give you confidence and fulfillment in life.
Having a pet to welcome you when you get home is another wonderful feeling! Check your local shelter and adopt one if you can...creating two happy lives. 
Blessings,
