I don’t think you should overcome it, why don't you enjoy it...don't run from your thoughts, hear yourself. Appreciate your environment, the air, the wind, the birds... Anything in your surroundings. I love my loneliness because of that... you feel lonely because you think no one is caring about you...so care for others, then you will think you're important. You're not lonely. You have you talk with yourself. ...and explore, read, try to learn new things, plant flowers  and look after them. At least you have mobile phone. Then you will find another person in yourself and don't need others. I'm not saying separate yourself from others try to have memories with family and friends. Love yourself.
