actually I feel the same way right now.....
I'm gonna get out and get a part time job
I think then I'll maybe meet some new people and feel a tad more productive
Gosh, there's so many things you could do to stay busy and give you some purpose like volunteering somewhere. You don't know how badly they need volunteers! Everywhere, from the Salvation Army bell ringers, to helping out in shelters or gathering food, etc. for the shelters, visiting nursing homes, helping in animal shelters. They always need dog walkers, etc! You name it. This could keep you busy and give you some purpose rather than moping around the house feeling useless. You're not useless! You are young and can do so much! Just look around you. I think you'll come up with something. :)
