holy ****. I honestly could have written this. I'm going through exactly the same thing. I enjoy doing things and going out sometimes, but it's not fulfilling to do it alone. I transferred schools and I'm finding it impossible to make a connection with anyone. no one seems willing to let me in. I dream of traveling somewhere, but it's impossible when you're poor and have to choose between eating and making rent. I go places but my loneliness drowns me, so I go back home where no one is waiting and consume mindless entertainment until my eyes are sore and my mind is numb.
sorry for the rant. but I feel your pain. I really do. hope you'll get out of this funk soon. it sucks.
